All Add-ons are disabled and Firefox still can not play SOME of the videos on twitter. All I can see is a spinning circle on the center of the frame and the video will never be played. I tried other browsers and they all works well. It seems this issue has nothing to do with my network connection.

I searched this forum and find out some thread reporting issues of not playing All videos on youtube/twitter. Replies to these thread provided some solutions ,like update ffmpeg , set media related options in about:config. I tried them all and neither of them work for me.

I reinstalled the Visual C++ and Firefox loaded when i ran the Firefox repair but totally locked up. Unable to get to settings or any website and will not run after closing it.

The latest version of firefox for MacOS 14.4.1 has broken the picture in picture function. When enabling PiP, the video window takes up almost the entire screen and doesn't remember the size i set it to, like it did in older versions of Firefox. Another issue is when im in fullscreen mode and enable PiP, the PiP window takes me to another 'desktop', whereas before it would simply overlay on top of my screen.

How do I turn off those annoying "update available" notifications/reminders that keep popping up? I've gone into Settings, and in the Updates section firefox only let's me select auto updates or check for updates. I searched online but couldn't seem to find anything about how to disable the notifications all together with the newer version of FF. It's driving me crazy, thinking of switching browsers because of this. Thanks in advance!

Since upgrading to the last version, 125.0.3 I'm getting tab crashes. Is there any way to go to a previous version? I have not had any issues with the websites I'm visiting until this new version of Firefox.

Hi everyone!

Jack here. I am a non-tech person and don't know the technicalities behind this issue. I have a Digital Media Website which loads and works quite fine when opened in other browsers but the site is loading very slowly in Mozilla and when it does load it has breakages.

Can anyone please tell me what the issue might be and how to fix it?

Thanks, Jack

So I'm having issues playing 4K videos fully on one YouTube channel: https://www.youtube.com/@ClearviewDriving

For some reason anything above 1080p gives me bad stuttering but on other channels videos don't stutter or freeze when playing 1440p or 4K quality.

Firefox is updated, I don't use Extensions other than Ad Blocker and I have that off on YouTube anyway. Seems strange that it'd only affect one specific channel.

I have a very good gaming PC too so the hardware isn't the issue.

The increase happened here: /storage/permanent/chrome/idb/3870112724rsegmnoittet-es.files/

79 files taking 590MB created in 3 minutes, out of nowhere. Why were all these large files created?

Using Linux Mint, Firefox 125.0.2

I want to delete firefox logins info and to make sure passwords and logins are never stored. I go to passwords, open up menu, and the "remove all passwords" choice is greyed out. How can I get that choice it be valid and to impliment that operation?? And to never have these stored??

I am afraid to update to Firefox 124 for fear of losing the existing order of 100s of open tabs if the default setting of ordering tabs by "Recently Opened" kicks in before I have a chance to change the setting to "Tab Order". Can anyone help me? I'd like to upgrade to 124 if I can do so safely!
