I hear people say they encounter sites like this (and I believe them), but apart from I think one local government website, I don't think I've actually ever encountered a site that straight up says it won't work with Firefox (and actually doesn't work with Firefox).
But I share your concern about a Chromium monopoly. Even If I strongly preferred Chromium (which I don't) I'd be really worried if Firefox went away and we were left with only Safari for Apple folks, and Chromium for everyone else. That would be bad for everyone.
Although it technically works, Mega and some other "download" sites are far less functional in Firefox because Mozilla (correctly) won't implement the unsafe, non-standard API's that Mega et al depend on.
Similarly, Mozilla won't implement hardware management nonsense like WebUSB, so the sites and devices that use that crap won't work in Firefox.
This sub gets regular complaints about both of these things. And that's my biggest fear with Google running the show. When we talk about privacy, security, and so on, it's not just junk like telemetry and cookies. It's google (and its users) explicitly not caring about those things at a grand scale, making the web as a whole less safe and private for the sake of ease of use and convenience.
I know it's a cliche accusation, but google at this point really is a cancer making the internet objectively a worse place to be. But god forbid if little Jimmy can't update his GaMEr MouSE in the dumbest way possible.
> Trello will literally tell you firefox is not a supported broweser, strangely enough it does seem to work fine
Just visited Trello using Firefox. No issues and they did **not** say anything about Firefox not being supported.
Usually it only means that they don't test it in Firefox, so they can't guarantee it will work.
But it may also mean, that some specific features won't work.
Maybe he is using Firefox ESR, which is most likely not considered "Latest" (it's receiving "feature updates" only once a year).
For example, current Firefox ESR 115 is almost a year old now and it's missing A LOT of new JavaScript and CSS features. The good news is, new Firefox ESR 128 is almost here:

/u/Niikoraasu, please do not use Pale Moon. Pale Moon is a fork of Firefox 52, which is now over 4 years old. It lacked support for modern web features like Shadow DOM/Custom Elements for many years. Pale Moon uses a lot of code that Mozilla has not tested in years, and lacks security improvements like Fission that mitigate against CPU vulnerabilities like Spectre and Meltdown. They have no QA team, don't use fuzzing to look for defects in how they read data, and have no adversarial security testing program (like a bug bounty). In short, it is an insecure browser that doesn't support the modern web.
*I am a bot, and this action was performed automatically. Please [contact the moderators of this subreddit](/message/compose/?to=/r/firefox) if you have any questions or concerns.*
I agree. I have only encountered one site that told me Firefox was not a supported browser but when I refreshed, it worked fine. I haven't seen this anywhere else. If it does become worse, I really hope that they find a way around it.
I have an example of which site doesn't work on Chrome, Cinemex in Mexico, that site is so broken, only works on Chrome or Edge.
Yeap, there're other examples as well, sometimes you don't get every feature if you are using Firefox.
[https://webcompat.com/](https://webcompat.com/) apparently this is something to enforce internet web page design standards and you can like file ocmplaints or something? IDK never heard of it before yesterday, saw someone else post it on a thread with a similar subject matter.
Firefox on desktop now has an in-browser reporter for compatibility issues - menu -> Report broken site.
Please be specific, and please especially report sites that say they don't support Firefox
Basically the same system that [webcompat.com](http://webcompat.com) feeds into. It doesn't always get as much info, but it's much lower friction and more discoverable than [webcompat.com](http://webcompat.com) for users.
Of course, a fair number of reports are just broken sites or a bad network connection, but still it gets a lot more signal.
i'd say use firefox as your main, but have base chrome installed, blank, so if it doesnt support you can just copy and paste straight into chrome and then when you're done close chrome completely. No need to switch your entire browser because of a doctors site
Yeah I sometimes use Edge since that's installed anyways. Only really need it for family calls in Google Meet, but well, handy to have it around for that.
I'd say use Firefox as your main, and when you encounter a website that doesn't "support" Firefox then write to them.
A website doesn't need to "support" web browsers these days. A website needs to be written to standards, and then it will work in every browser. Very, very few sites need to push to boundaries of technology to provide their functionality.
That capability went away when they killed xul addons. The best you can do is send a tab to another browser, which still requires a helper program outside of Firefox.
Ah, yeah that's different, just tricks the website into thinking you're using a different browser, not guaranteed to work for all websites. I was referring addons way back in the day that would literally run a different browser engine inside a custom tab.
You aren't alone. The Premium Bonds (NS&I) website here in the UK says it doesn't support Firefox when you visit it on Android. No other Android browser I've used has that issue.
Firefox on desktop now has an in-browser reporter for compatibility issues - menu -> Report broken site. You can just say in the report it's for android
Yeah, it says this .
What about FF can't they get working ?
The following browsers are below our threshold for support. Some functionality may still work.
* Mozilla Firefox
* Microsoft Internet Explorer
* Brave
* Opera
* UC Browser
They do exist, the problem is that people think they have to switch your browser when they encounter one or two. It seems an alien concept that instead of actually switching you can just keep a compatible browser for the fuse sites which require it.
I needed something confirmed on a phone application by opening some page in the browser -> click on a confirmation link -> automatically would then open in my app and the thing will be confirmed. Granted I had to install something chromium based because the link opened in Firefox would not do the trick and the app would not recognize it. So I installed Brave, set it up as default browser for that time and then proceeded once again with the required steps. \*suprised pikachu face\* it worked.
It's a shitty situation but many developers ignore the fact that users do use Firefox..
They generally do't say that, but I've come across instances where something just doesn't work:
-order process for my internet contract was simply stuck without message, went ahead in Chrom
-for FF on Android there are multiple food delivery websites where the payment process opens the Play Store link to download the payment app instead of the payment app
-Teams links don't open the Teams meeting and I have to copy the link into Chrome/Edge
Firefox on desktop now has an in-browser reporter for compatibility issues - menu -> Report broken site.
For the android food delivery sites, just say it's for android. Thanks!
Same. Honestly i’m in the same exact boat. I’m not fully sure what’s going to happen to firefox and i’m unsure about its future in the web browser market. Because although there’s still about 176 million monthly active users, the management and the leadership seems to get worse especially after the latest Mozilla drama. I really do want firefox to succeed and there to be another competitive web engine. But more and more sites I use are only supported by chromium and that seems to be the general consensus on this subreddit as well.
You don't have to use exclusively a single browser. It sucks that lousy webdevelopers do not bother to try Firefox. But, you can keep some chromium browser installed to switch when needed, but still use Firefox as the main driver.
Now if this is for a larger environment besides your personal I can totally see the issue, if the people above do not care for the cause they won't listen to any Firefox purist position about "but think of the web!", and simply suggest change Browsers because immediate cashflow dictates decisions. For that, we have little more than webcompat and complain to sites that don't support Firefox :(
Personally, I very very very rarely have ran into a site that does not support Firefox, then again, when a single website doesn't work for people, they'll be pretty quick to say "Firefox doesn't work" in an absolutist way.
>It sucks that lousy webdevelopers do not bother to try Firefox.
Very rarely is it the developers making that decision. That comes from management and/or stakeholders. They don't want to spend the time/money on testing against Firefox, and will often tell the developers just to slap a "not supported" message on there so they don't have to deal will people telling them it doesn't work on Firefox.
My daughters school lunch money website has bugs in Firefox that causes me to have to use edge for orders. I also do software development and last month our security team reached out to me and told me to uninstall Firefox because it was decided it's not approved software now. They didn't care that I develop and test several public websites and and test with chrome and Firefox. That was a sad uninstall for me.
It sucks watching my favorite piece of software lose market and mind share. Remember the media attention it got years back with the new Javascript engine? It's add on system has been gimped but is still better than all the other options too. I fear the worst for Firefox and would gladly pay or donate $10/month if that meant it would survive. Too bad all you can do is donate to the opaque Mozilla foundation and not to Firefox directly.
You did not have to heed their words and uninstall perse, a [user agent switcher](https://addons.mozilla.org/en-US/firefox/addon/chameleon-ext/) would've worked just the same.
For what its worth, [webcompat](https://webcompat.com/) might've help you in this field as, sadly, most people tend to view Firefox as not a "[world licensed browser](https://www.reddit.com/r/firefox/comments/c91qr6/world_licensed_browsers/)", whatever that means.
I have never seen a single website telling me that it does not support Firefox and I should start using chrome. Although many websites load frustratingly slow on Firefox e.g. YouTube. I guess all google services or services relying on Google do not work well in Firefox. But I am fine with it as I mostly browse those websites that do not give me a headache. What I am not fine with is Firefox using a lot of system resources to run. Which is why I use Edge in my office as I can't upgrade that computer because of company's policy. Firefox works fine on my home pc with Linux.
On YouTube, now, I'm using:
\* Fully updated Firefox
\* Fully updated Ublock Origin
\* User Agent Switcher and Manager
It works very well… Prior to Firefox 127.0.02, like many others, I was experiencing major issues with YouTube, to the point that I switched to Edge, or Opera, in order to watch videos. However, since the update, it's been buttery smooth. Though, I've read some people are still having problems; it seems extremely variable.
[Slack still supports Firefox](https://slack.com/help/articles/1500001836081-Slack-support-lifecycle-for-operating-systems-app-versions-and-browsers-Slack-support-lifecycle-for-operating-systems-app-versions-and-browsers#browser-support-lifecycle). You should only see that message if you're running an outdated version. I get it in Floorp because Floorp is based on ESR and reports itself as version 115.
They just said, "Slack says it won't support Firefox after September 1, 2024." According to the support page I linked, that means they're on 117 or lower. Though as I mentioned above, Floorp, based on the latest ESR, reports itself as 115, so they may be on a fork or official ESR (assuming official ESR reports as 115, too).
Well from the perspective of someone making the sites, why would you optimize to make it work in an engine only a tiny minority uses.
Yeah it sucks for the users, but:
* Your bosses don't want to spend money, they want to make money.
* You're being paid too little as a web dev anyways in most countries.
* This is your dayjob, not your passion project.
* Your manager already has 10 more things lined up you need to do.
* You just want to go home.
We've fostered a situation where adherence to web standards is actively disliked by all sides of the process making the web. Different reasons, but nobody is going to look out for them. As a result, if "Just make it work in Chrome!" is good enough for all business the business conducts, then well, that's what you do!
I don't see many issues, both on my Android phone and on my Linux desktop.
For the occasional side where I need Google chrome, I will create a shortcut for Chrome just for that website. The main issues using microphone and stuff like that which is baked into Chrome.
Otherwise I find that Firefox satisfies all my needs and I am horrified by its decline.
I have been using Firefox as a daily driver in my IT career for roughly 10 years now. I have never encountered a site that does not work with this browser or that I couldn't make work with a quick user agent change. I feel like all you got to do to make this browser work well is slap on ublock origin the tree style tabs and away you go. I mean the corporate stuff that's going on at Mozilla right now is really depressing but besides that the browser seems to be impeccable. I don't even have issues with youtube BC of ublock origin.
I don't think there's any other browser company out there right now that is trying to do what Mozilla is doing even if they are doing it badly. Everyone else is focused on making profit for their shareholders which will result in the inevitable enshitification, only Mozilla is the one that keeps trying to do things for the betterment of the public.
Yes, I've come across several sites that don't support FF or don't load/work correctly in FF. It's so frustrating. I don't want to shift away from FF but more and more lately I'm wondering if I should just bite the bullet and try something else. My biggest concern is finding one that will have the same add-ons that I use in FF.
I am confused
We already had IE monopoly, read this nice post to learn more: http://toastytech.com/evil/ieisevilstory.html
And people didnt like that, so we started to get more browsers and sites started to support them
Now we are getting to a monopoly again, and for what, just because people are lazy and want to use someone else web engine instead of writing their own
The decline in web compatability is a side effect of most other browsers switching to Chromium, sadly.
Mozilla could have prevented this quite easily.
Windows Sysadmins asked for Group Policy support. Mozilla gave us ESR.
Chrome offered GPO support way before Firefox (IIRC) and so people switched from IE.
I think we've hit the point where soon, *all* we will have is Chromium. These days, Mozilla can't even get the execution of vertical tabs right. They just implemented it into Nightly and...well, just take a look at it as it sits now compared to Floorp.
https://preview.redd.it/269ketll519d1.png?width=1280&format=png&auto=webp&s=40b6bcc39c1f3b8b46dc395b8e2e368040835fa3
This is Nightly. Note the off-centered buttons there, and no, this is not a panel that pops out and auto-hides, nor is there a close button on hover.
While I can't attach a shot of a window in Floorp here (that will be in a reply to this post), this isn't true of it. BEFORE this implementation existed in vanilla, they had a vertical tab bar that popped out on over, had a close button for the tab, and did all this with minimal issues. It's a little buggy when you go to customize the browser, sure, but click the restart command they have in the menu right above exit and it's fine. The UI looks as polished as it can be given the hacky nature in which it's implemented, and it works well enough.
Floorp doesn't stop there, though. They have a PWA system in place for web apps, something Mozilla pulled out of vanilla FF because it didn't work as they wanted and now refuse to re-implement. It even has a workspace system similar to how it works in Edge, something Firefox points to container tabs for. ***And it's doing this with a team considerably smaller and with much less resources than Mozilla gives to Firefox.***
Firefox's demise is one of Mozilla's own making, and I really think the damage is done. They say save the web, and yet, albeit only briefly, they cater to the whims of the Russian government and block anti-censorship extensions in Russia. They say they recognize that the internet is part of modern life and be open and accessible, and yet drag their feet for QOL additions found in almost every other major browser since 2012. They say that they believe the individual should be able to shape the internet and their experiences on it, yet refuse to try to implement PWA support for web apps in a successful manner again, also running against innovating on the web, something Firefox hasn't been doing for years now. They say transparency is key, yet actively fought against the developers of the aforementioned restricted extensions as to why, effectively forcing them to determine why on their own, shattering their promise of "community-based processes" promoting "participation, accountability and trust." And all of these promises were pulled from the Mozilla Manifesto, a document that...well, I think I've proven is only a document that ALSO shatters that goal for accountability and trust.
This is the world they made. This is what they now must live in. Turns out being willing to take in millions of dollars from your major competing force to have their search engine as your default and remaining content to be a distant 2nd place is only going to in the end make you LOSE to that competitor.
https://preview.redd.it/laewle1l819d1.png?width=1280&format=png&auto=webp&s=ce5f36a9fb8ecf295e337b58d86f4f2ef05c2eba
And here's that Floorp screenshot. Forgot to mention they also have a proper sidebar like what you'll find in other popular browsers too, not just another place where bookmarks and history lives.
When creating request to a website, a certain addon can spoof the header with custom value and that can be (e.g. Chrome user-agent). By reading the value in user-agent, most websites detect which browser you're using.
Take a look at: https://addons.mozilla.org/en-US/firefox/addon/user-agent-string-switcher/
WebUSB, Filesystem API, PWAs, etc.
That's exactly the type of stuff that gets people to try another browser and leave Firefox if it gets too annoying switching between browsers.
I feel like Firefox's main selling point is not copying the fuck-ups that are kneecapping uBlock Origin and filling their product with (intrusive) ads and/or telemetry (although Firefox does ship with some telemetry and ads by default.) But ultimately that will only get them so far, I believe marketshare is still declining and I think they really aren't in a position to use Firefox to protest against these APIs or features. Big scary warning, sure, but just not having these APIs in any capacity isn't a good idea in my opinion.
**Edit:** Some corrections: Firefox does appear to support some parts of the Filesystem API, namely with "OPFS" (a virtual filesystem specifically for a website?). My understanding is that this doesn't allow the type of access that, say, `vscode.dev` requires.
I should also note that Safari is also very conservative in what APIs it supports, it doesn't even support WebMIDI, which Firefox sort of supports, but was kinda clunky to activate last time I tried. So I guess Firefox can say they're teaming up with Safari in defending the web against APIs like WebUSB.
**Edit 2:** Firefox not supporting WebUSB is a shame because it's really neat for stuff like QMK VIA. These type of web-based programs are a great way to have easy cross-platform compatibility. (For those who haven't used it in Chrome et al., you get a screen where you have to choose the device you want to give access to, it doesn't automatically have access to all devices).
WebUSB could be used to do all sorts of nefarious things, unfortunately. And a website that's OK today to have access because you trust them might be compromised by a hacker tomorrow, or sold to a malware site or a ransomware group.
OPFS is a safe subset of the Filesystem API, which allows storing files for an origin that only that origin can access. It doesn't allow access to the rest of your disk like the Filesystem API does. See previous point for why this can be dangerous, especially as people aren't going to want to approve access to each and every file. Adobe Photoshop Web makes \*extensive\* use of OPFS for example
Unpopular opinion; but Firefox seems fastest to and feels more responsive to me on Windows 11. Even more than Edge and Chrome, and it is coming for someone who has been using chrome since day 1.
I'm experiencing the same.
I'm now banned from booking trains in my country, since using Firefox trigger some new "unusual behavior detected" message on that website. Fantastic. It's like there's a server-side attack on users now, with site owners trying to make sure you're not a deviant - just like you'd be punished for daring to have access to the admin (root) account on your Linux phone.
We're getting massively dumb.
Just to mention a website that didn't work properly in Firefox ESR, I wanted to order something from the Square Enix Web Store and the payment field where you could select between Credit Card, PayPal etc. just never appeared. Or rather it did appear for a split-second and then it vanished so I sadly had to resort to Edge for my order.
Granted that might be an ESR thing, I'm using ESR because it still has the old Windows Vista Glass code that you can beautifully with Windows 11's Mica. I understand that the UI is probably the last thing that Mozilla at large worries about at the moment but it's a bummer as I still remember how nice Firefox looked during the Vista days.
I can't see me ever switching from Firefox as my main browser (I've been using it since FF 2.0) but currently my biggest gripes with Firefox that have me use Chromium every now and then:
\- Lack of HDR Support. Since getting a HDR monitor watching video-content feels lacking on Firefox, especially with Nvidia's TrueHDR being able to add HDR to non-HDR videos which only works on Chromium
\- Lack of PWA support. It's nice to be able to open specific websites quickly as their own window from shortcuts without having to worry about manually opening a new window
\- The UI. Thankfully Firefox's UI is still hightly customizable but I still wish we would get native, proper Mica support and a more rounded UI as most operating system lean into this aesthetic. I was also never a fan of Firefox drawing its own title-bar ignoring the system one since Windows 8 as it clashes with themes. Now I can't complain about that as Windows custom themes aren't officially supported in the OS but I want to put it out there. The latest version of the Notepad app shows how beautiful a titlebar with tabs can look in Windows 11. But I'm happy Firefox finally gets native vertical tab support as that's my preferred way of using tabs nowadays.
I think i have only had issue with a few university webtools. But honestly nothing breaks in native firefox. Things break as i have ETP on strict, ublock origin, and localcdn installed.
If things bother me enough i switch to a barebones firefox profile and if its still broken i use https://webcompat.com/
It's also Firefox fault. Mozilla paying the CEO millions while Firefox is leaking engineers and becoming slower and slower.
If Firefox was the fastest with nice features power users would come back. And power users usually influence non power users and it would cycle back
It just feels gross telling people to try opening websites on Edge instead of FF. I had began running into browser functionality problems many years ago, and FF let me configure advanced settings to have non-standard behavior. I needed to have multiple tabs stay active, even when they weren't the visible tab. FF has since removed the ability to override that setting, but the different software companies that needed that feature have moved on. More recently, our software providers have been swapping out stand alone features for Chrome plugins. That has relegated my use of FF from work to only personal browser, but I'm beginning to see the cracks in that as well. Twitch integrations have been failing, with notes from their devs that FF is no longer supported. As much as I prefer this browser to any flavor of chrome, I don't see any way forward if devs don't see a reason to support the browser.
The only site I've ever seen that doesn't support Firefox is twitch. And apparently you can get around it with some work. Honestly, I just stopped using twitch though.
I've never had problems with Twitch on W10, [also they support all the mainstream browsers](https://help.twitch.tv/s/article/supported-browsers?language=en_US)
He's a sysadmin. He can't just ditch Windows in a corporate environment. And more importantly, what has the Firefox vs Chrome debate to do with Windows? These asshole design websites will force you to Chrome based browsers on Linux too.
I use CUDA. And weird USB peripherals with Windows-only drivers. I'm stuck. Plus I play video games that don't work on Linux. I'm well and truly stuck.
Kinda. I love using FOSS when I can, and I use a ton of it, but some work I do on the side requires proprietary software that works pretty well and has no open source alternative. That software demands I use an Nvidia GPU. I like to play video games in my downtime on the same hardware and video games are very rarely open source. Many I play don't work on Proton.
That said, even in a vacuum, Linux and I don't work well together. I stopped using Windows entirely in university, and I spent *years* distro-hopping, trying to find a distro and DE that worked for me. Never found one that quite worked the way I want. Ubuntu Xfce came close, but I had to switch away due to persistent compositor issues. Ubuntu MATE was really fun, I love MATE's design, but I couldn't customize it the way I wanted. KDE Plasma was pretty and had the most modern featureset but it was worse for battery life than Windows 10 was on the hardware I was using at the time. Manjaro was a total clusterfuck and I had to reinstall my OS multiple times due to bad dependencies delivered through the official repo. Maybe I'm a little bitch but I never got used to pacman either.
So yeah I'm back on Windows now. It works really well. Watching my ripped Blu-Rays in HDR works effortlessly, all my games work, all my software works, and my years-old Windows 10 install that I've carried on an SSD between multiple computers is miraculously stable. Completely worry-free.
I guess we reached the stage of "The early 2000s called and want their _This site is optimized for Internet Explorer_ back". I agree, it's a shame.
I hear people say they encounter sites like this (and I believe them), but apart from I think one local government website, I don't think I've actually ever encountered a site that straight up says it won't work with Firefox (and actually doesn't work with Firefox). But I share your concern about a Chromium monopoly. Even If I strongly preferred Chromium (which I don't) I'd be really worried if Firefox went away and we were left with only Safari for Apple folks, and Chromium for everyone else. That would be bad for everyone.

What is the (final?) system that both of these "feed" into?
Generally bugzilla bugs in the Web Compatibility -> Site Reports area
There's no universal browser compatibility reporting system? Cross-browser

You can still do this with extensions 😉
That capability went away when they killed xul addons. The best you can do is send a tab to another browser, which still requires a helper program outside of Firefox.

Ah, yeah that's different, just tricks the website into thinking you're using a different browser, not guaranteed to work for all websites. I was referring addons way back in the day that would literally run a different browser engine inside a custom tab.
Well, looks like it is time to look for a new doctor😅
Dr. Frankenstein ?
Dr. Acula. I don't recommend.
You aren't alone. The Premium Bonds (NS&I) website here in the UK says it doesn't support Firefox when you visit it on Android. No other Android browser I've used has that issue.
Firefox on desktop now has an in-browser reporter for compatibility issues - menu -> Report broken site. You can just say in the report it's for android
Ok that's good to know. Thank you.
PG&E’s website started saying that a couple months back. (It still works though.)
Yeah, it says this . What about FF can't they get working ? The following browsers are below our threshold for support. Some functionality may still work. * Mozilla Firefox * Microsoft Internet Explorer * Brave * Opera * UC Browser
I assume it’s not a matter of “can’t get working” but more “don’t want to spend the time and money to test it and guarantee it works.”
Firefox on desktop now has an in-browser reporter for compatibility issues - menu -> Report broken site.
They do exist, the problem is that people think they have to switch your browser when they encounter one or two. It seems an alien concept that instead of actually switching you can just keep a compatible browser for the fuse sites which require it.
I needed something confirmed on a phone application by opening some page in the browser -> click on a confirmation link -> automatically would then open in my app and the thing will be confirmed. Granted I had to install something chromium based because the link opened in Firefox would not do the trick and the app would not recognize it. So I installed Brave, set it up as default browser for that time and then proceeded once again with the required steps. \*suprised pikachu face\* it worked. It's a shitty situation but many developers ignore the fact that users do use Firefox..
They generally do't say that, but I've come across instances where something just doesn't work: -order process for my internet contract was simply stuck without message, went ahead in Chrom -for FF on Android there are multiple food delivery websites where the payment process opens the Play Store link to download the payment app instead of the payment app -Teams links don't open the Teams meeting and I have to copy the link into Chrome/Edge
Firefox on desktop now has an in-browser reporter for compatibility issues - menu -> Report broken site. For the android food delivery sites, just say it's for android. Thanks!
Teams, the web version says it doesn't support Firefox.
[https://kbworks.eu/teams-web/](https://kbworks.eu/teams-web/)
Interesting, thanks
Neither do Firefox developers apparently.
What sites?
Same. Honestly i’m in the same exact boat. I’m not fully sure what’s going to happen to firefox and i’m unsure about its future in the web browser market. Because although there’s still about 176 million monthly active users, the management and the leadership seems to get worse especially after the latest Mozilla drama. I really do want firefox to succeed and there to be another competitive web engine. But more and more sites I use are only supported by chromium and that seems to be the general consensus on this subreddit as well.
I have literally zero issues with FF. What sites are you visiting?
Snapchat web. Also the increasing number of sites on this subreddit reporting that firefox is no longer working with them is sad to see.
Snapchat web works with a user agent switcher
So it actually works but they lie?
Well a few of the " tricks" they use to detect if you are pressing buttons don't work iirc. But yes, other than that it works perfectly.
So one page momentarily not working makes you doubt an entire web browser and company?
You don't have to use exclusively a single browser. It sucks that lousy webdevelopers do not bother to try Firefox. But, you can keep some chromium browser installed to switch when needed, but still use Firefox as the main driver. Now if this is for a larger environment besides your personal I can totally see the issue, if the people above do not care for the cause they won't listen to any Firefox purist position about "but think of the web!", and simply suggest change Browsers because immediate cashflow dictates decisions. For that, we have little more than webcompat and complain to sites that don't support Firefox :( Personally, I very very very rarely have ran into a site that does not support Firefox, then again, when a single website doesn't work for people, they'll be pretty quick to say "Firefox doesn't work" in an absolutist way.
>It sucks that lousy webdevelopers do not bother to try Firefox. Very rarely is it the developers making that decision. That comes from management and/or stakeholders. They don't want to spend the time/money on testing against Firefox, and will often tell the developers just to slap a "not supported" message on there so they don't have to deal will people telling them it doesn't work on Firefox.
My daughters school lunch money website has bugs in Firefox that causes me to have to use edge for orders. I also do software development and last month our security team reached out to me and told me to uninstall Firefox because it was decided it's not approved software now. They didn't care that I develop and test several public websites and and test with chrome and Firefox. That was a sad uninstall for me. It sucks watching my favorite piece of software lose market and mind share. Remember the media attention it got years back with the new Javascript engine? It's add on system has been gimped but is still better than all the other options too. I fear the worst for Firefox and would gladly pay or donate $10/month if that meant it would survive. Too bad all you can do is donate to the opaque Mozilla foundation and not to Firefox directly.
Yeah, I'm also a developer and my company blocked Firefox on employee PCs last year
Wow, this seems like madness instead of encouraging devs to test on multiple platforms…
You did not have to heed their words and uninstall perse, a [user agent switcher](https://addons.mozilla.org/en-US/firefox/addon/chameleon-ext/) would've worked just the same. For what its worth, [webcompat](https://webcompat.com/) might've help you in this field as, sadly, most people tend to view Firefox as not a "[world licensed browser](https://www.reddit.com/r/firefox/comments/c91qr6/world_licensed_browsers/)", whatever that means.
I have never seen a single website telling me that it does not support Firefox and I should start using chrome. Although many websites load frustratingly slow on Firefox e.g. YouTube. I guess all google services or services relying on Google do not work well in Firefox. But I am fine with it as I mostly browse those websites that do not give me a headache. What I am not fine with is Firefox using a lot of system resources to run. Which is why I use Edge in my office as I can't upgrade that computer because of company's policy. Firefox works fine on my home pc with Linux.
The YouTube thing is intentional
On YouTube, now, I'm using: \* Fully updated Firefox \* Fully updated Ublock Origin \* User Agent Switcher and Manager It works very well… Prior to Firefox 127.0.02, like many others, I was experiencing major issues with YouTube, to the point that I switched to Edge, or Opera, in order to watch videos. However, since the update, it's been buttery smooth. Though, I've read some people are still having problems; it seems extremely variable.

[Slack still supports Firefox](https://slack.com/help/articles/1500001836081-Slack-support-lifecycle-for-operating-systems-app-versions-and-browsers-Slack-support-lifecycle-for-operating-systems-app-versions-and-browsers#browser-support-lifecycle). You should only see that message if you're running an outdated version. I get it in Floorp because Floorp is based on ESR and reports itself as version 115.
[удалено]
Comment has since been deleted, what was their version?
They just said, "Slack says it won't support Firefox after September 1, 2024." According to the support page I linked, that means they're on 117 or lower. Though as I mentioned above, Floorp, based on the latest ESR, reports itself as 115, so they may be on a fork or official ESR (assuming official ESR reports as 115, too).
im just a hobby computer enthusiast, but i feel u
Well from the perspective of someone making the sites, why would you optimize to make it work in an engine only a tiny minority uses. Yeah it sucks for the users, but: * Your bosses don't want to spend money, they want to make money. * You're being paid too little as a web dev anyways in most countries. * This is your dayjob, not your passion project. * Your manager already has 10 more things lined up you need to do. * You just want to go home. We've fostered a situation where adherence to web standards is actively disliked by all sides of the process making the web. Different reasons, but nobody is going to look out for them. As a result, if "Just make it work in Chrome!" is good enough for all business the business conducts, then well, that's what you do!
I don't see many issues, both on my Android phone and on my Linux desktop. For the occasional side where I need Google chrome, I will create a shortcut for Chrome just for that website. The main issues using microphone and stuff like that which is baked into Chrome. Otherwise I find that Firefox satisfies all my needs and I am horrified by its decline.
I have been using Firefox as a daily driver in my IT career for roughly 10 years now. I have never encountered a site that does not work with this browser or that I couldn't make work with a quick user agent change. I feel like all you got to do to make this browser work well is slap on ublock origin the tree style tabs and away you go. I mean the corporate stuff that's going on at Mozilla right now is really depressing but besides that the browser seems to be impeccable. I don't even have issues with youtube BC of ublock origin. I don't think there's any other browser company out there right now that is trying to do what Mozilla is doing even if they are doing it badly. Everyone else is focused on making profit for their shareholders which will result in the inevitable enshitification, only Mozilla is the one that keeps trying to do things for the betterment of the public.
Yes, I've come across several sites that don't support FF or don't load/work correctly in FF. It's so frustrating. I don't want to shift away from FF but more and more lately I'm wondering if I should just bite the bullet and try something else. My biggest concern is finding one that will have the same add-ons that I use in FF.
Stay true in your support of Firefox. There should never be a monopoly in browsers, let alone a Google monopoly.
I am confused We already had IE monopoly, read this nice post to learn more: http://toastytech.com/evil/ieisevilstory.html And people didnt like that, so we started to get more browsers and sites started to support them Now we are getting to a monopoly again, and for what, just because people are lazy and want to use someone else web engine instead of writing their own
i haven't seen a site that only supports chrome in like 10 years.
The decline in web compatability is a side effect of most other browsers switching to Chromium, sadly. Mozilla could have prevented this quite easily. Windows Sysadmins asked for Group Policy support. Mozilla gave us ESR. Chrome offered GPO support way before Firefox (IIRC) and so people switched from IE.
I think we've hit the point where soon, *all* we will have is Chromium. These days, Mozilla can't even get the execution of vertical tabs right. They just implemented it into Nightly and...well, just take a look at it as it sits now compared to Floorp. https://preview.redd.it/269ketll519d1.png?width=1280&format=png&auto=webp&s=40b6bcc39c1f3b8b46dc395b8e2e368040835fa3 This is Nightly. Note the off-centered buttons there, and no, this is not a panel that pops out and auto-hides, nor is there a close button on hover. While I can't attach a shot of a window in Floorp here (that will be in a reply to this post), this isn't true of it. BEFORE this implementation existed in vanilla, they had a vertical tab bar that popped out on over, had a close button for the tab, and did all this with minimal issues. It's a little buggy when you go to customize the browser, sure, but click the restart command they have in the menu right above exit and it's fine. The UI looks as polished as it can be given the hacky nature in which it's implemented, and it works well enough. Floorp doesn't stop there, though. They have a PWA system in place for web apps, something Mozilla pulled out of vanilla FF because it didn't work as they wanted and now refuse to re-implement. It even has a workspace system similar to how it works in Edge, something Firefox points to container tabs for. ***And it's doing this with a team considerably smaller and with much less resources than Mozilla gives to Firefox.*** Firefox's demise is one of Mozilla's own making, and I really think the damage is done. They say save the web, and yet, albeit only briefly, they cater to the whims of the Russian government and block anti-censorship extensions in Russia. They say they recognize that the internet is part of modern life and be open and accessible, and yet drag their feet for QOL additions found in almost every other major browser since 2012. They say that they believe the individual should be able to shape the internet and their experiences on it, yet refuse to try to implement PWA support for web apps in a successful manner again, also running against innovating on the web, something Firefox hasn't been doing for years now. They say transparency is key, yet actively fought against the developers of the aforementioned restricted extensions as to why, effectively forcing them to determine why on their own, shattering their promise of "community-based processes" promoting "participation, accountability and trust." And all of these promises were pulled from the Mozilla Manifesto, a document that...well, I think I've proven is only a document that ALSO shatters that goal for accountability and trust. This is the world they made. This is what they now must live in. Turns out being willing to take in millions of dollars from your major competing force to have their search engine as your default and remaining content to be a distant 2nd place is only going to in the end make you LOSE to that competitor.
https://preview.redd.it/laewle1l819d1.png?width=1280&format=png&auto=webp&s=ce5f36a9fb8ecf295e337b58d86f4f2ef05c2eba And here's that Floorp screenshot. Forgot to mention they also have a proper sidebar like what you'll find in other popular browsers too, not just another place where bookmarks and history lives.
Floorp looks really nice!
Should there be a Chromium container for Firefox? Would it be a feasible idea?
screw chromium, once manifest v3 hits that entire subset of browsers is fucked, stick with firefox.
No excuse when you have Firefox with user agent switching.
what is that
When creating request to a website, a certain addon can spoof the header with custom value and that can be (e.g. Chrome user-agent). By reading the value in user-agent, most websites detect which browser you're using. Take a look at: https://addons.mozilla.org/en-US/firefox/addon/user-agent-string-switcher/
I'm pissed off by its lack of WebUSB support. Their stance on certain standards is absurd.
WebUSB, Filesystem API, PWAs, etc. That's exactly the type of stuff that gets people to try another browser and leave Firefox if it gets too annoying switching between browsers. I feel like Firefox's main selling point is not copying the fuck-ups that are kneecapping uBlock Origin and filling their product with (intrusive) ads and/or telemetry (although Firefox does ship with some telemetry and ads by default.) But ultimately that will only get them so far, I believe marketshare is still declining and I think they really aren't in a position to use Firefox to protest against these APIs or features. Big scary warning, sure, but just not having these APIs in any capacity isn't a good idea in my opinion. **Edit:** Some corrections: Firefox does appear to support some parts of the Filesystem API, namely with "OPFS" (a virtual filesystem specifically for a website?). My understanding is that this doesn't allow the type of access that, say, `vscode.dev` requires. I should also note that Safari is also very conservative in what APIs it supports, it doesn't even support WebMIDI, which Firefox sort of supports, but was kinda clunky to activate last time I tried. So I guess Firefox can say they're teaming up with Safari in defending the web against APIs like WebUSB. **Edit 2:** Firefox not supporting WebUSB is a shame because it's really neat for stuff like QMK VIA. These type of web-based programs are a great way to have easy cross-platform compatibility. (For those who haven't used it in Chrome et al., you get a screen where you have to choose the device you want to give access to, it doesn't automatically have access to all devices).
WebUSB could be used to do all sorts of nefarious things, unfortunately. And a website that's OK today to have access because you trust them might be compromised by a hacker tomorrow, or sold to a malware site or a ransomware group. OPFS is a safe subset of the Filesystem API, which allows storing files for an origin that only that origin can access. It doesn't allow access to the rest of your disk like the Filesystem API does. See previous point for why this can be dangerous, especially as people aren't going to want to approve access to each and every file. Adobe Photoshop Web makes \*extensive\* use of OPFS for example
Chromium's WebUSB API implementation necessitates that the user provide manual permission to access attached devices.
Unpopular opinion; but Firefox seems fastest to and feels more responsive to me on Windows 11. Even more than Edge and Chrome, and it is coming for someone who has been using chrome since day 1.
Firefox is my main, Brave is my secondary, Chrome is my last resort.
Same! Arc browser is the new kid on the block and looks promising. https://arc.net
I also run FF ESR in my environment. Honestly I think I've never seen any site break or say "try chrome instead" for that matter.
I'm experiencing the same. I'm now banned from booking trains in my country, since using Firefox trigger some new "unusual behavior detected" message on that website. Fantastic. It's like there's a server-side attack on users now, with site owners trying to make sure you're not a deviant - just like you'd be punished for daring to have access to the admin (root) account on your Linux phone. We're getting massively dumb.
Just to mention a website that didn't work properly in Firefox ESR, I wanted to order something from the Square Enix Web Store and the payment field where you could select between Credit Card, PayPal etc. just never appeared. Or rather it did appear for a split-second and then it vanished so I sadly had to resort to Edge for my order. Granted that might be an ESR thing, I'm using ESR because it still has the old Windows Vista Glass code that you can beautifully with Windows 11's Mica. I understand that the UI is probably the last thing that Mozilla at large worries about at the moment but it's a bummer as I still remember how nice Firefox looked during the Vista days. I can't see me ever switching from Firefox as my main browser (I've been using it since FF 2.0) but currently my biggest gripes with Firefox that have me use Chromium every now and then: \- Lack of HDR Support. Since getting a HDR monitor watching video-content feels lacking on Firefox, especially with Nvidia's TrueHDR being able to add HDR to non-HDR videos which only works on Chromium \- Lack of PWA support. It's nice to be able to open specific websites quickly as their own window from shortcuts without having to worry about manually opening a new window \- The UI. Thankfully Firefox's UI is still hightly customizable but I still wish we would get native, proper Mica support and a more rounded UI as most operating system lean into this aesthetic. I was also never a fan of Firefox drawing its own title-bar ignoring the system one since Windows 8 as it clashes with themes. Now I can't complain about that as Windows custom themes aren't officially supported in the OS but I want to put it out there. The latest version of the Notepad app shows how beautiful a titlebar with tabs can look in Windows 11. But I'm happy Firefox finally gets native vertical tab support as that's my preferred way of using tabs nowadays.
Can you report the square enix thing via the in-browser reporter? Menu->Report broken site.
Sure I can do that!
I think i have only had issue with a few university webtools. But honestly nothing breaks in native firefox. Things break as i have ETP on strict, ublock origin, and localcdn installed. If things bother me enough i switch to a barebones firefox profile and if its still broken i use https://webcompat.com/
never heard it even exists that some sites not support firefox \^\^ but cant complain never had or have problems with firefox, totally happy :D
hmm.... no list of sites + is there any moderation for the publications, or are we heading to any trash post?
> More and more sites are breaking in Firefox. Please provide evidence backing up your claims. Posting URLs will do.
It's also Firefox fault. Mozilla paying the CEO millions while Firefox is leaking engineers and becoming slower and slower. If Firefox was the fastest with nice features power users would come back. And power users usually influence non power users and it would cycle back
It just feels gross telling people to try opening websites on Edge instead of FF. I had began running into browser functionality problems many years ago, and FF let me configure advanced settings to have non-standard behavior. I needed to have multiple tabs stay active, even when they weren't the visible tab. FF has since removed the ability to override that setting, but the different software companies that needed that feature have moved on. More recently, our software providers have been swapping out stand alone features for Chrome plugins. That has relegated my use of FF from work to only personal browser, but I'm beginning to see the cracks in that as well. Twitch integrations have been failing, with notes from their devs that FF is no longer supported. As much as I prefer this browser to any flavor of chrome, I don't see any way forward if devs don't see a reason to support the browser.
The only site I've ever seen that doesn't support Firefox is twitch. And apparently you can get around it with some work. Honestly, I just stopped using twitch though.
I'm on MacOS 10.14 Mojave and Firefox 115 ESR and Twitch is working for me. Twitch ad block solutions are still not perfect, but that's another story.
I've never had problems with Twitch on W10, [also they support all the mainstream browsers](https://help.twitch.tv/s/article/supported-browsers?language=en_US)
Twitch works fine w firefox on Linux
Twitch works for me on firefox, are you sure you're using the latest versions?
I just checked, must be working now. Like I said, I just stopped using twitch when it stopped working so I'm not sure when it was fixed.
twitch works fine on firefox (windows 11)
You're on Windows, are you? Just drop that M$ spyware OS and get Linux. Far more choice available there.
He's a sysadmin. He can't just ditch Windows in a corporate environment. And more importantly, what has the Firefox vs Chrome debate to do with Windows? These asshole design websites will force you to Chrome based browsers on Linux too.
That doesn't address OP's main problem with Firefox. OS has nothing to do with the question.
Telling a sysadmin to drop Windows for Linux when its "equivalent" of group policy is utterly tragic. Alright mate.
Far more choice of what, exactly? Well-supported browsers? Incredibly unlikely.
Great if you're a software dev, not so great if you do any other kind of intensive work on your computer.
?
I use CUDA. And weird USB peripherals with Windows-only drivers. I'm stuck. Plus I play video games that don't work on Linux. I'm well and truly stuck.
so its not actually the operating system in general. its your attachment to proprietary software.
Kinda. I love using FOSS when I can, and I use a ton of it, but some work I do on the side requires proprietary software that works pretty well and has no open source alternative. That software demands I use an Nvidia GPU. I like to play video games in my downtime on the same hardware and video games are very rarely open source. Many I play don't work on Proton. That said, even in a vacuum, Linux and I don't work well together. I stopped using Windows entirely in university, and I spent *years* distro-hopping, trying to find a distro and DE that worked for me. Never found one that quite worked the way I want. Ubuntu Xfce came close, but I had to switch away due to persistent compositor issues. Ubuntu MATE was really fun, I love MATE's design, but I couldn't customize it the way I wanted. KDE Plasma was pretty and had the most modern featureset but it was worse for battery life than Windows 10 was on the hardware I was using at the time. Manjaro was a total clusterfuck and I had to reinstall my OS multiple times due to bad dependencies delivered through the official repo. Maybe I'm a little bitch but I never got used to pacman either. So yeah I'm back on Windows now. It works really well. Watching my ripped Blu-Rays in HDR works effortlessly, all my games work, all my software works, and my years-old Windows 10 install that I've carried on an SSD between multiple computers is miraculously stable. Completely worry-free.
