Firefox Support Forum

Ever since Firefox updated to the new version I've been having constant crashes. I've tried restarting in Safe Mood which doesn't help. Pretty much Firefox will open, say it's not responding, and then by the time it looks like it's about to restore my tabs it crashes. I had to do a refresh and transferred the backup files from an older session which worked, but then it eventually crashed again. I uninstalled and reinstalled Firefox and tried opening my older profile but it keeps happening. I really need to restore my previous session. There's nothing with my computer that seems to be causing it. I did have 2 windows open with about 8,000 tabs total which I'm sure could be part of the reason, but it never really had trouble before and only just started crashing since the update. Is there any way to fix this without starting over? I read that this is a bug that others have dealt with previously.

Some additional information. I'm on a 64-bit Windows 10 PC.

Hello there to all.. I have been experiencing occasional crashes on the tab when left idle for a while!! I am using Ubuntu linux 22.04 when this occurs..! In Windows 11 or even Windows 10 x64 pro this does not occur to my knowledge at all.. So I am wondering why this is happening only on ubuntu linux 22.04 and not anywhere else??.. Anyways, Thanks for listening and have a great day ahead also..

So i downloaded firefox from the website... it doesnt even open! i tried to reinstall which didnt solve the problem.. then i uninstalled and installed it from the MS Store... it opened once and i used it for a day, but then the next day.. it again crashed and didnt open.. i didn't have extensions nor any themes. PLease help.. i used it everyday in win10... but in win11, edge or chrome is the only option.. pls fix it ASAP

I am a Firefox user for 5 years now and never had such bad experience before. Since 2022 February 8 my Firefox application keeps crashing all the time. The browser opens and I can open webpages as well, but shortly after opening the websites, most of the pages result in Firefoxing crashing. I have latest version of Firefox and I have checked in safe / troubleshooting mode as well, but it did not help, Firefox still crashes. I have submitted a lot of crash reports in the last two days, the latest one has this ID: bp-94f69edd-95cb-40e3-84de-33cb20220210.

Please let me know what to do, as currently I cannot use Firefox and without a fix I have change to another web browser. Please also note that the same webpages that crash under Firefox work without errors in other browsers.

First of all , Hello  :) FF is a great wb and i use it everywhere i got a machine. Works fine everywhere .. but here on this computer. Why only on this machine ? Same distros ( linux mint 20.3 ) radeon video cards , amd family cpu's This machine is AMD FX(tm)-6300 Six-Core Processor × 6 the video card atm is AMD PITCAIRN (DRM 2.50.0, 5.4.0-94-generic, LLVM 12.0.0) though i had the same crash issue with a nVidia graphics card. Memory is Corsair and the memtest86 reports no errors. This is where i get a bit lost. Memory issues or hardware defects might explain this but where's one to begin ? Trouble is , no other application ever crashes and it's rock solid. So is FF to point a finger at or something else ? That's the objective of me submitting this report. Try to find out what's really at fault here and fix it.

The crashes happen at all times. It can also be right at starting FF and never even reaching the main window. I tried with and without the --safe-mode and it's the same that also happens.

So i submitted one of the crash reports ID: 656264f4-7867-4c55-8b36-0637e0220114

The report can be found here : https://crash-stats.mozilla.org/report/index/656264f4-7867-4c55-8b36-0637e0220114

Since there's so many i hesitate to put them all up , there's dozens since the system reinstall yesterday , i reinstalled the whole OS again yesterday to try to get rid of the bug. Any help to solve this once and for all will be highly appreciated . :) thanks for reading

I'm having an issue where Firefox (Linux, 96.0.3) will crash after it's been running for a while but no crash report is generated. This is on an older Intel NUC with 2GB RAM running Clear Linux and intended to be used as a digital sign. No other applications are running. There is only a single tab loading a single page from localhost. No extensions are installed. The page is a simple layout using CSS grid. Javascript is used to create a slider with four slides, to cycle through a series of videos hosted locally, and periodically check for content updates. Below is the JS in it's entirety.

My feeling is that it's a memory issue, possibly to do with the video playlist, but I've been monitoring memory usage via about:performance and the tab with the sign has never used more than about 5MB. I've also been monitoring the system resources via htop and I've never seen it go higher than about 1000MB. How can I track down this issue?

Thanks in advance!

Hello, After FireFox update on 2-4-2022, FireFox crashes in seconds after startup and uninstall & reinstall does not help. I tried the uninstall & reinstall several times now. I am very frustrated. I have been using FireFox browser for many years not and have many bookmarks that I don't want to lose. Please help.

Has Mozilla stopped processing crash reports for older versions of Firefox like Firefox ESR v52.9.0 (the legacy version for Win XP and Vista)? I tried to filter crash reports on the Mozilla Crash Report site at https://crash-stats.mozilla.org/home/product/Firefox for older versions of Firefox but I can't select a Firefox version older than v68.4.1 (i.e., the current FF ESR version) - see attached image.

I'm trying to assist a Vista SP2 / Firefox ESR v52.9.0 user who is trying to troubleshoot their browser crashes but they've told me they are having problems submitting their crash reports from about:crashes. I just want to make sure that Mozilla is still processing crash reports for older version of Firefox if the user submits them from about:crashes manually, assuming the crash report is less than 6 months old.

The past week or two it has been acting haywire and crashing daily. I uninstalled, re-installed, re-started computer. Nothing helps. I have attached picture of error message. windows 10 firefox version 92

Firefox has been running fine for me for a long time but recently, like the last week or so, it has been crashing constantly. When I first boot up my computer, it will be fine for awhile and then it'll just crash. If I try to restart it then, it will either immediately crash or crash after a few seconds. sometimes it will hold together for a bit and then crash. I've had it crash when I've clicked to move to a new webpage, and I've had it crash when it is just idling on a webpage. I have already tried troubleshooting mode and it still crashed, so its not my extensions. Ive also tried to reinstall it and that has not helped either. Any help would be greatly appreciated.

After this last update Firefox is really slow loading pages and has crashed on me multiple times, I have also noticed if the browser is up it slows other programs down now like when im burning a cd. Is anyone else experiencing this? Thank you

Hi, I'm very lost as to why Firefox has suddenly starting crashing on me very frequently over the past 3 or so days, after Firefox's latest update. I first noticed it when I tried watching streams on Twitch, then I also noticed it on YouTube, and then when casually browsing Reddit. I've gone through all the troubleshooting steps:

• I've made sure Windows is up to date
• Firefox is up to date
• My drivers are all up to date
• There are no viruses/malware/any issues with my firewall settings and computer security, I've tested and checked everything
• The crashes DO still happen in Troubleshooting Mode
• I've checked my RAM using Windows Memory Diagnostic for errors and there are none
• I've refreshed Firefox, I've cleared my cache, I've done an entire clean uninstall and reinstall of Firefox
• I'm able to watch streams, videos, and browse Reddit just fine on my other devices and on Google Chrome. This is only an issue I'm encountering with Firefox, which is super disappointing because I've never had a single issue in the past several years I've been using it as my browser ):

I've submitted so many crash reports because it's been crashing so often, but here's the Report ID of the most recent: bp-0b0dac91-ec69-4c9e-a8c0-a622b0220116

I'm so confused and have no idea why this is happening. Any help at all would be greatly appreciated. Thanks!

Hi, for the past week whenever I open Firefox (FF) it works normally for about two minutes, then slows, then causes my entire mac to slow and freeze. If I don't force quit FF quickly, my mac crashes. Once I force quit FF everything is fine. I've been using Chrome for the past week or so hoping FF would fix itself with an update but no go.

Anyone else having this issues?

Firefox (and chrome, but not edge) crashes on startup. There's no crash report. The window shows up as an outline for a fraction of a second and then is gone. It doesn't show up in task manager. I've uninstalled and reinstalled multiple times. I've updated windows and my antivirus. I've tried a few other fixes that came up from searching for a fix, but so far nothing has helped.

FireFox started crashing at FireFox launch. Tried reboot, tried refresh, uninstalled and re-installed, tried Safe Mode. Thought it was a new extension, but apparently not.

Hi all, first time poster,

Very frequent firefox crashes has rendered the program almost useless, seems to continue to get worse as well. Minimal plugins enabled. Crashes still occur in Troubleshoot mode. No third party modules. Have also played around with performance mode. All continues to happen, in fact happened on this tab as I was typing this. Below are my recent crash reports. Any assistance - or if I need to post additional info - is appreciated. Thanks!

For some reason, randomly, and now this is occurring more and more frequently, Firefox will just hang and say that "Firefox is not responding," and I have to wait ~30 seconds for it to unfreeze and continue using Firefox. I have tried every potential solution that I could find on the Internet, such as disabling hardware acceleration, creating a new places database, etc., and I still keep getting these 30 second freezes on a pretty frequent basis. Do you guys know what might be going on?

Firefox crashes when attempting to view google maps street view. I have completed refresh, uninstall and reinstall. Went back to older version ESR to try that with no luck
