Firefox Support Forum

I've noticed lately that my Firefox keeps freezing and hanging up at random periods for no apparent reason. I have very few plugins and it even happens with them all disabled and removed. I've tried resetting Firefox to default everything yet it makes no difference.

Also I can not clear history. I've tried multiple different clear history plugins but none of them work at all. And when I try the traditional way of clearing Firefox history the window pops up and then the entire browser just freezes while 'clearing' and never gives me back control, I have to force quit and restart to regain control. And then when I relaunch the history is still not cleared!

So aside from the constant lagging and lockups it seems that any attempt to delete history whether using the inbuilt function or adding plugins messes up the whole browser.

Googling this issue it seems others are having the exact same problem with Firefox and yet any suggested solutions (reset browser) don't seem to be working for may of them.. Or me.

I've been having problems with some websites not displaying content, others displaying error messages. So have been going through the Troubleshooting Mode and diagnostic process.

The cause is the MS CoPilot extension for Firefox.

Useful in other ways as I discovered several other extensions I don't need, hence have remained disabled.

Recently upgraded to a new laptop, Thinkpad X1 Carbon 11th gen. Running a Wayland-based WM. OpenGL is working fine everywhere except Firefox. Works fine in Chrome, Blender, glxgears, Steam games. Firefox 121 gives the following error:

[GFX1-]: Failed to compile vertex shader: gpu_cache_update [ERROR webrender::device::gl] Failed to compile vertex shader: gpu_cache_update

Confirmed that MOZ_ENABLE_WAYLAND=1 is set.

I am a bookkeeper and use QuickBooks Online (QBO)(AUS version) as my preferred accounting program, Intuit recommends using Chrome, but I had problems with that too, in that it has fields in QBO that will not work, I have switched to Firefox because it handles the 'black' look and the columns within the ledgers are more stable, however Firefox is constantly crashing it can recover most times to where I was, but it is most infuriating. Question is, is this a known problem and can it be fixed by changing the settings? Geoff Woodford

Why, with not very many active open windows, and just after opening, is FF using 175% of my CPU, not counting all the separate listings in my Activity Monitor. Plus it's using nearly all 16 GBs of my RAM. With every new update, I pray it will mean the browser will just work, and not use up all my computer's resources, but it just never does. Pretty soon, more & more of us will just give up on this browser, which used to work better, years ago, and has only gone downhill since.

I seem to have gotten something called Google Ad Services. It frequently interferes with my getting to websites and I cannot find how to block it or remove it. HELP!

I recently made the switch to Firefox. I attempted to use the version downloaded from the internet, which I already had installed for a long time, but it would not open. I then used the version available on the Microsoft Store, which worked fine. Eventually, Firefox crashed and would not reopen. A message saying something along the lines of "Are you sure you want to start Firefox in safe mode?" would appear for a split second, and then close. I tried:

-Starting Firefox in safe mode, but nothing happened. -Restarting my computer. -Reinstalling Firefox. -Running as administrator. -Checking it is not blocked by antivirus. -Using the profile manager to create a new profile: The .zip file version opens but does not help, and the version opened by using the "firefox.exe -P" command in Run suffers from the same problem as the browser and opens for only a split second. -Attempting to boot my computer in safe mode with networking, however, the Microsoft Store listed Firefox as uninstalled, and the network menu would not display any networks so I could not reinstall it. -Searching for any Comodo iseguard.dll files, but I found none.

The only thing that worked was searching "Mozilla" in files and deleting everything except what my computer said was part of the system. After that, I was able to open Firefox, but after a short amount of time, the problem started all over. I have no clue what to do and looking all over for solutions is driving me nuts! Please help!

A while ago I formatted my computer, and installed FireFox for the first time. Ever since installing FireFox, I noticed an issue which has been a constant source of frustration, when I rewind any YouTube video the playback volume changes to a lower value, until I rewind again.

I tried looking online, this is the closest match I've found, but there's no solution there

I tested this issue on different browsers (Edge, and IE), no problems there. I tried disabling extensions, no change. I tried resetting FireFox, no change. I made sure that Windows doesn't automatically adjust system volume. I tested this issue on different Video platforms, no problems there.

I use YouTube when I practice (music), so I rewind a lot.

Any help is very appreciated.

Hi......,

I have had firefox browser for a while now and it has always worked fine. Now I`m suffering from that internet pages can`t be loaded ( see attachment ). I think,am not sure since the last update. The weird thing is that youtube does work and can just play video`s also 4K. I have read the error report but can`t really do much with it. Is there anyone who can help me in the right direction?

Thanks in advance for the trouble.

I've always used Firefox browser instead of Microsoft Edge, and I would like to continue using Firefox. However, it will not run in its current form under Windows 11. Does Mozilla plan to keep it compatible with Windows? I would like to keep using Firefox.

I don't need any images, you know the problems ... Freezes, no internet access.

Greetings. I can't open most sites I usually visit (even google.com) via my Firefox 98.0a1. This happens since today. All error codes are SEC_ERROR_LIBRARY_FAILURE.

Tried to:

• Disable DNS-over-HTTPS.
• Disable HTTP/3.
• Disable proxy (never had it enabled anyway).
• Disable sending info to Firefox developers.
• Change settings of DNS-over-HTTPS.
• Restart the browser (after each action).

Nothing helps me... But I still can visit some websites, but most common resources are not working for me. Please help me because I can't use Microsoft Edge without getting mentally ill. :/

For a few days now, I have not been able to play videos. I get this message in the video screen: "If playback doesn’t begin shortly, try restarting your device." When I opened Firefox in Troubleshooting mode, the video played OK and then when I stopped Troubleshooting mode the videos continued to play OK. However, on the next day the problem reappears. What's going on? Thanks in anticipation, Frank

Firefox is becoming more and more buggy and more unstable using more than 8Gb of ram in either the apps processes or if not there then in the background processes and when you look into the firefox task manager it reports it is using no more than maybe 100 MB of ram the only way to stop it is to close the one process that is using all the memory. when i investigate using the about:memory function it tries to tell me that it is an extension using the memory but if i disable the 2 extensions i use and reload the measure memory it still is using exactly the same amount of memory. is there any sort of fix for this because i am getting sick of having to have the windows task manager open to close the rogue process every time i use my browser

Please help me remove this blank area section on the web pages. its on all of them on every tab. I have tried restarting and updating. I cant get it to go away.

thank you Mark

I've had a problem recently with some sites (such as support.apple.com, but also others) loading very slowly or not loading at all.

• Restarting Firefox fixes it for a short while
• I've tried changing to No Proxy from Use System Proxy Settings - this, like restarting, helped for a short while
• Unchecking DNS over HTTPS: DID resolve the problem but I'm curious as to why. I enable it with Safari with no problem.

When I try to download a file, the download always fails. This happens no matter what website I'm downloading the file from (see screenshot 1).

This started happening within the last week or so. We are running versions 97 and above.

Firefox is configured to always ask where to save files to (see screenshot 2).

Write permissions to the user's Downloads folder is denied for reasons unrelated to this issue (see screenshot 3). When I re-enable write permissions, the problem goes away.

Has anyone else run into this problem? Is write access to the Downloads folder required now, even if Firefox is not configured to save files to that location? Thanks!

This is happening every few minutes now. It started right after the 97.0.0 update. The 97.0.1 update doesn't seemed to have helped.

I don't use any browser extensions.

I never saw this issue before, and I have been using Firefox as a primary browser for many years. I'm on a MacBook Air, M1.

All of a sudden I can no longer access a website that I have visited a million times before. I get an error message stating...

The page isn’t redirecting properly

Firefox has detected that the server is redirecting the request for this address in a way that will never complete.

   This problem can sometimes be caused by disabling or refusing to accept cookies.

I have cleared cookies/cache and all that achieves is that I can get to the website's log in page but then straight back to the same error message. I'm so frustrated as this is a website I need to access for my work.

I can get to it no problem on my phone so it appears to be a Firefox issue. I don't want to use another browser as I get on well with firefox but I fear I may have to as this is too important a website to be without.

Any help would be appreciated - thank you, Nat

This is a horrible web browser that crashes constantly and is slow as hell. Even Internet Explorer is faster than this, and I am switching to that browser and am never reinstalling Firefox ever again.

The behavior of FireFox saving PDF files has changed. I am using WIN10, FireFox 98.0.1 and have it setup to use windows default application and always ask where to save for PDFs.

BEFORE the problem: The PDF opens in Acrobat Pro IX. After clicking save I would be asked, where to save. I select the location to save the PDF. Then after this, subsequent PDFs downloaded would be saved to the last saved location. This process would repeat for a new website PDF load and save. This is the behavior I want now.

NOW with the problem: The PDF opens in Acrobat Pro IX. 1. Immediately, after a reboot, the save icon on Adobe is grayed out. I select save as and point to the desired directory. 2. For any subsequent PDF opened, the Adobe save icon is available. Files are saved to the desktop.

Please note I believe I once did get a popup asking where to save and I know I selected desktop.  Since that selection I am no longer asked where to save.

Please note I have looked and tried some of the suggestions at: https://support.mozilla.org/en-US/kb/cant-download-or-save-files#w_choose-a-different-download-folder

but some of this advice needs to be updated for the new FireFox version--ex no JSON file is found at the file location covered in the advice.

I believe this issue started after the last FireFox update. Please help me restore behavior listed above under “BEFORE the problem”. Thanks.
