Firefox Support Forum

basically just the title. In the last couple days youtube.com specifically has been borderline unusable for me on firefox. All other websites work fine for me on firesfox and youtube has no issues on other browsers.

I have been playing a game on facebook for years. 4 days ago It stopped working. Other players are saying that they had to switch browsers ( to Chrome and others) and they are able to play the games. Why can I not play on Firefox?

Support,

The USPS website does not work properly with Firefox!! The Home page loads okay but there are multiple other issues with links not working. For instance all of the links under Quick Tools do not work except this one: https://www.usps.com/manage/po-boxes.htm. Other things don't work either.

Everything works fine that I tried with Google Chrome though! Please address soon.

Thanks

Hello, about 1-2 weeks ago a very strange problem occurred - on some pages videos don't play at all or play without a sound. Can anyone help me with this strange situation? For example, every video on youtube.com plays without a problem; on facebook.com every video plays with no sound at all; on some other pages video doesn't play at all. This problem is only with firefox, if I try to open the same videos with another browser everything is fine.

When I try to play a video on Firefox desktop, it takes it a long time to load. Once it has loaded, whenever I pause it for more than a few seconds, or if I try to skip around the video (either by clicking around in the loaded section of the progress bar or using +/- seconds buttons), the video begins buffering again before the video resumes. This makes it extremely difficult and frustrating to watch anything that requires me to pause, rewind, or fast forward. I've noticed this issue affect multiple video viewing sites, such as YouTube, Vimeo, and Netflix. My roommate also uses Firefox, but doesn't have this issue, so I know it's not a problem with my internet. I thought it might be a problem with my computer, but I tried to replicate the issue in Chrome and everything worked fine there. The issue has persisted almost a week. I have:

• Rebooted my computer several times
• Deleted my history/cache
• Disabled my extensions
• Turned off Java scripts in firefox (this disabled my ability to load sites like YouTube completely, so I turned it back on)
• Updated my computer
• Updated my graphics drivers
• Refreshed firefox
• Uninstalled and reinstalled firefox (and rebooted my computer)
• Uninstalled and reinstalled firefox AND deleted all the data it stored on my computer (and rebooted my computer)

I am currently using version 123.0.1 of Firefox. My OS is Windows 10 22H2.

Mozilla account in Firefox PC browser always asks to re-login every 1 day. This problem appeared after updating Firefox from version 119 to 120 and 121.

As in the image below, "Account Disconnected" and a triangular warning appears in the Firefox menu bar. I can't access any sync data like passwords, bookmarks, plugins if I don't re-login.

I only use this mozilla account on 1 PC.

YouTube all of a sudden started to slow down and only be able to load videos fast enough in 360p resolution, I tried watching YouTube on Microsoft edge and YouTube handled 1080p easily there, I have cleared the cash and made sure my Firefox and Windows are up to date and still the issue persists.

this only seams to occur on YouTube as amazon prime and speed test works without issues

Last night, when I got home from work, my Firefox browser wouldn't let me make any Google searches or log into my Google account. It just keeps coming up with the end of file error. I've refreshed Firefox, created a new profile, turned off Proxy, uninstalled NordVPN, and even tried to uninstall/reinstall Firefox. After refreshing, I can sometimes search with Google for a little bit until I try to log into my Google account or navigate to Gmail while not logged in. It also won't let me access Yahoo.com, it seems. It will do random websites, though. For example, I entered the url for a video game forum I've browsed in the past and it loads that okay. Any suggestions? Do I have a virus or something? I honestly can't figure this out.

I'm having problems with Firefox using 75% of processor capacity. In "top" I see many instances of "Isolated Web Co".

At the moment of this screen shot the processor is not overwhelmed, however, it will sometime jump up to 75% and the system will seem to freeze.

What is the "Isolated Web Co"? I'm thinking a virus.

Thank you.

Firefox crashes whenever I use ctrl v or right click, and pulls up a window that it crashed. Whenever I start it back up, it says it wasn't able to restore session, then restores it anyway after I press to restore it. Another thing is whenever I try and upload a file onto a site it crashes as well. I'm on Mac OS x 13 and reinstalling firefox hasn't fixed it. This is relatively sudden, it happened about around 3 days ago for the first time, and at the same time I noticed it happening certain sites also started giving me '502 Bad Gateway' errors. Does anyone know what's happening and how to fix it? Thanks in advance!

How can I turn this message off? Some sites I visit give me that message, it shows up when I'm typing a reply to something which pushes the page lower and fouls up my ability to keep typing, then if goes away, comes back, goes away ... I just want to kill the message entirely. I'm not worried about speed, there's nothing to fix, I just want the message gone.

Hi, I have a problem starting yesterday. When I video chat with anyone using Firefox on FB messenger they can see me but I cannot see them. Only a black screen where they should be showing. I have tried everything from uninstalling to different settings. I have made sure also that permissions were set correctly. Also it has been giving the error "slowing page down" or what says. Nothing helps. Now if I use Edge or phone it works just fine and we can see each other. This has never happened before. Also, the messenger games wont work on firefox either, but will on others. Please help if possible or tell me how.

Thank you

For the past 3 months or so, anytime I try to login to Sony Playstation website I can't get past entering my email. After putting in my email and hitting next the website slows and firefox slow crashes. I have to force firefox to close. I have tried leaving a message to Playstation Twitter support. I've noticed their sign in page has change a few times recently so I wonder if it's an issue they caused. Either way it would be appreciated if it was looked into. Always feels like a lot of websites only care about chromium. By the way it works fine on edge or chrome. It also does not work with private browsing, so I don't think it's my extensions or cookies. I have also tried multiple computers.

Hello! I need some help. Every since 4-6 months ago, Firefox has been extremely slow when I boot it up at first, with some page load times taking more than 10 minutes. Some fixes have seemed to work, but they never work permanently. From my testing, it is not the result of any extension and the issue persists in troubleshoot mode. What has not helped my testing is that, after enough restarts of Firefox, the problem goes away and web pages load quickly, so this has caused some false positives. Has anyone else had a similar problem they were able to fix? Should I try uninstalling Firefox and reinstalling it?

I have a Lenovo ThinkPad X1 Yoga Gen 6 (20XY005MGE) with Win11 Pro.

All of a sudden, Firefox does not play any sound. I notice that it does not show up in the volume mixer. I tried:

• this solution: https://support.mozilla.org/de/questions/1278299
• Reboot the PC
• Uninstall and reinstall Firefox
• Deactivate all Extensions
• I worked my way through the manual pages (none of which mentions Firefox missing in the volume mixer)

Youtube does not play sounds, the Spotify page notices that it cannot play sound (the spotify App for Windows works fine, though). News sites (tagesschau.de / video, deutschlandfunk.de / audio) play the video, but no sound.

I had the problem a few months ago already but I cannot recall the solution :(

Thanks for helpful hints!

Stop tabs from automatically refreshing to top of page. Many people have this problem and I don't find a fix. One article states to go to Options and "Warn me when websites try to redirect or reload the page," but I can't find options.
