Despite being listed as supported on: https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/enumerateDevices

enumerateDevices() still only returns input devices. Running navigator.mediaDevices.enumerateDevices().then(devices => console.log(devices)); in the Firefox console only shows input devices while on Chrome it shows output devices.

I use a website that supports playing from multiple output devices so when receiving a phone call, your desktop speakers and your headset can ring at the same time. This works in Chrome but it doesn't in Firefox.

Apparently Firefox updated overnight and now my New Tab Page, which had a ton of tiles on it that I'd pinned over the years is now completely blank, no tiles, no nothing (except the Firefox logo). If there were at least some blank tiles, I'd have something to work with, but when I say blank, that's exactly what I mean.

Is there any way to get back the tiles I had? Because none of the pages I've opened or searched so far has created a tile on the page.

Thanks.

I keep getting this message- With firefox I get this message: Close Firefox Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window.

I have followed the instructions to resolve this, but none of them are working.

For the past few weeks Firefox has been crashing and freezing often. Crashes are worst when trying to access Protonmail, which almost always crashes the tab instantly. Freezes happen most often when browsing Reddit, and also when watching Youtube, but crashes and freezes can happen on almost any website.

I have tried changing profiles, refreshing and uninstalling/reinstalling, but the problem persists and seems to be getting worse over time.

Here are some recent crash reports:

I restarted Firefox on my Mac earlier, which I think updated it from 136 to 137. After reopening it, web pages won’t load anymore. They either time out or just load indefinitely without doing anything. I went through the troubleshooting page and tried reinstalling it, which didn’t help. My computer’s firewall is off as well. I’ve tried refreshing it multiple times, and I get a message that Firefox has crashed before it actually refreshes. After that, pages will load normally for a very short amount of time (about 30 seconds) before stopping again. Pages are still loading normally on Chrome and Safari, so it’s only Firefox that’s having an issue. Does anyone have any solutions for what this could be/ways to fix it?

I like firefox...used it two to three times a week for over ten years...Now when I click on the icon on my menu, I am greeted by the ansurb: "That doesn't look right." When I try to download Firefox, it will not down load...why are you idiots doing this to your own product?

When I open Firefox it opens a maximized window with tabs, then it opens a minimized with a single tab, then it reopens a maximized window with all session tabs. Each window displays in succession, one window at a time.

I'm on desktop using Windows 11.

I just read a post saying this behavior was caused by the resist fingerprinting feature. Can someone explain how that causes the repeated opening of browser window 3 times. Is there a way to retain the anti-fingerprinting behavior w/o the multiple window opening behavior?

Hello,

Hopefully this is something that can get answered quickly. These past few days I have not been able to use FireFox on my laptop.

It doesn't seem to be a wifi connection issue because other browsers work and other devices are connected just fine.

I also tried opening FireFox in the "troubleshoot" mode, but I am still receiving the same errors. I would appreciate any help I can get on this issue.

Below is a screenshot of the error I keep receiving.

Thanks,

Tried the standard checks for lose cables and refresh monitor rate etc but pc monitor still blinks off and on when trying to access sites like Tumblr and Amazon.co.uk. The websites work fine without issue on my laptop, just my pc seems to have the issues, googling suggests the issue might be firefox related so would appreciate any help

Kind regards

I am trying to access iDRAC 7 on a Dell Poweredge R520. On version 133.0.3 I get a An error occurred during a connection to 192.168.1.20. PR_END_OF_FILE_ERROR. I know that the problem is that Firefox stop supporting older versions of TLS. So I choose to also install an older version of Firefox (43.0). On that version I get a The page you are trying to view cannot be shown because the authenticity of the received data could not be verified error. I used to have no problems accessing iDRAC 7. Has anyone else been able to resolve this problem?

Hi, I’ve been experiencing slow performance on Firefox recently. It takes a long time to load pages, and the browser sometimes freezes when I have multiple tabs open. I’ve tried clearing my cache and updating Firefox, but the issue persists.

Has anyone encountered similar issues? Are there any tips or settings I should check to improve performance on a Windows machine? Thanks for your help!

So, i have a laptop, with integrated cpu graphics (Intel UHD) and discrete gpu (RTX 3060), first times when i set in Windows settings to use Firefox powerful gpu, it just won't, i tried restarting browser but i forgot that i have opened private tab, so i not restarted browser. So, on any pages like WebGL Aquarium, i have pretty low fps, in comparison to other browsers (like Microsoft Edge or Google Chrome). Then, after i see that tab, i closed it, and after restart i got my fps, but.. still lower than other browsers, on WebGL Aquarium with 30k fishes, Firefox max fps is around 35, but on Chrome is around 70 (two times faster). I found one page that shows gpu that uses for acceleration, and it shows pretty weird information in Firefox. https://kdashg.github.io/misc/webgl/low-power.html So, in Chrome it says like "Nvidia RTX 3060 Mobile GPU", and when i choose integrated gpu for this browser in windows, it says like "Intel UHD GPU", but, in Firefox, on first tries it said same, but when i got discrete gpu acceleration, it says that i have "Nvidia Geforce GTX 980". I was like, what? Where it did come from? This explains why I have a fps two times lower but who will explain to me why this gpu is here? I tried to change all acceleration settings in browser, but when i just disabled any acceleration, still shows GTX 980 what is more weird than if it just shows like nothing or Intel GPU, cause is disabled but still uses hardware acceleration, but no matters if i let Firefox use recommended performance settings or set to use acceleration when is available, it shows GTX 980. I think it's about a bug, or something? I can't say that's Windows problems, drivers, or any other thing, cause, other browsers don't act like this, and i just don't have GTX 980 in my laptop on side with RTX 3060 and Intel GPU, anyone even know that laptop like this exists? Screenshot don't wanna upload here so i decided to place it on imgur. https://imgur.com/pyMZQr0

I believe this problem began in 133. I've noticed that if FF is open for a few hours, it starts to develop a very noticeable input lag. For example, if I'm watching a YouTube video and hit an arrow key to advance the video, there will be a couple of seconds before the browser registers the key press. It behaves like a high CPU issue but I do not detect high CPU usage when this is happening. Restarting the browser resolves the issue for a few hours.

This is happening on Windows 11 as well as on a Mac running Sonoma.

When I open FF 137 on my iMac running OS 12.7.6, it just keep trying and trying with no link. When I try and quit it needs to be forced quick to stop running. There are no fire walls and it worked yesterday 4-5-25 just fine, but no go today. I tried replacing FF and still no luck, what do I try now, [email removed]@yahoo.com
