I am using Firefox on gnome desktop on the PureOS variant of Debian. About three days ago, I went to listen to my Spotify playlist on Firefox, not through the Spotify app. I had no sound, checked my system settings and turned the volume for Firefox from zero back up to normal. The rest of the song played, but when the next song came on, again no sound. I watched the sound settings and when the song finishes, Firefox disappears from the sound settings list. When the next song starts, Firefox is back in the list but volume is set back to zero. I suspect this may be something in gnome, but I thought I would check here in case anyone else is seeing this issue. Thanks so much for any help or at least a shoulder to cry on :D

On May 1st, when I launched Firefox(afternoon some time on US East coast) it ran an update to 138.0.1. When it was done, it did not launch. So I clicked the icon on my desktop and it came up, but then closed out after about 15 seconds. When I reopened it, it asked to continue in troubleshooting mode or refresh. I tried both. No luck. I restarted and even uninstall and reinstalled the latest version as well as tried installing 137.

I have tried with virus/malware protection/firewall off. I have restarted. My page file is default. I tried renaming the firefox.exe to something else. I tried creating an new firefox profile(firefox.exe -p) but that crashes too.

I installed the latest version of Firefox Nightly and it stays open just fine. But when I launch the regular firefox, they both close.

I also installed the Firefox app from the Windows store and it behaves the same as the one from the mozilla website.

As title says, whenever I'm scrolling through any website there's a lot of flickering, did some research and past "fixes" said to turn off smooth scrolling and hardware acceleration, which I tried but all it did was minimise the effects, this flickering has only been happening for the last day or so.

Firefox Developer Edition version - 139.0b1 (64-bit) Nightly version - 140.0a1 (2025-04-30) (64-bit)

Youtube video showing what's happening

I reinstalled FF on 30 Apr 25 and it performed normally for a few days.

It is now 3 May 25 and we're back to where we started.

I started FF and I'm getting the tour screen on one tab, the privacy notice on another

All the tabs I pinned are just spinning their wheels

And all my extensions are gone.

Hi,

there are massive performance issues while playing videos on Youtube while using Firefox. This does not happen with the same video while using edge. The attached video shows the used memory and CPU of the youtube tab from the firefox process manager. This was taken after playing the video for 30s. Letting it run longer resulted in firefox taking up 20GB of RAM.

I think this happens since I installed 138.0 of firefox.

Could you please take a look.

Thanks.

Best regards

Since the latest update, my Firefox is all screwed-up. I use Firefox only for Facebook. Since the update, about 2 weeks ago, nothing is right. When I click on the Firefox icon to open Facebook, what comes up is a log-in page (log-in info saved in Firefox). When I click on my user ID and enter my PW, the next window is Captcha. I have to go through the Captcha b.s. before FB opens. Never had a problem when I used Chrome. Guess I'll just uninstall Firefox and go back to Chrome. If there's a fix to the problems mentioned, please advise. Thank you.

I have a program up on cookingasmedicine.thinkific.com where students can go into my course and play videos. Everyone else can get the videos to play except me (the teacher) form my Lenovo computer. It used to work as I created the course with videos working. I can however see them operate on Internet Explorer! I have tried every setting, cookies, cache, etc. Nothing changes! This happened suddenly after an update about a year ago, it's been that long that I've been trying to get videos going again!

I called Thinkific and they can not recreate the video problem on their end - it's just my computer it seems. Other students using FireFox can see the videos as well - just not ME! It can't be my computer since I have been able to see the videos with no problems for years using this same computer. Now, I have to switch over to Edge or Internet Explorer in order to see the videos in my class program. Even if I uploaded new ones, they just won't play for me on my desktop. Thank you.

As of a few days ago (potentially coinciding with the most recent update?) I've had several websites become varying degrees of unresponsive when using Firefox while being connected to a VPN (Nord, in this case).

Some sites will load but then get throttled--i.e. YouTube will load and (usually) populate thumbnails, but clicking on a video will result in the video instantly dropping to its lowest available resolution, playing for a few seconds, and then stalling. Interestingly(?) if I try to watch a live stream, chat will be fully functional but the video will be unable to load. Other sites will load but then very quickly stop responding at all. Others are straight up just not loading period, while many others have no issues at all.

I've cleared my cache, deleted cookies for the affected sites, tried Firefox in a private window, tried Firefox with no extensions, and reinstalled both Nord and Firefox to no avail. All of the affected sites are fully functional so long as I'm not connected to a VPN, and are also fully functional on other browsers, even while connected to a VPN. All other non-browser related applications that require the internet are also unaffected, and my internet speeds in general aren't showing any issues.

I've been unable to find any other chatter about this anywhere, and I unfortunately don't have any other devices available to try and replicate the issues. I would not be surprised if it was one of those wonderful Me Exclusive DNS issues or something, but figured it was worth throwing out there.

Youtube is not working very well with firefox i deleted cash and temporary files and always updating but YouTube always stuck or not completing the video and sometimes not starting

Even though CPU and GPU utilization is very low during 8K60fps Youtube playback in the Firefox browser on my base M4 Mac mini, the struggles heavily to play this, drops tons of frames, and the video almost stops playing.

8K 30 fps is not problem, and since utilization is pretty low, that doesn't explain the poor performance.

So please optimize 8K60fps Youtube playback on all platforms in the safari browser, but especially on Apple SIlicon Macs.
