Firefox Community Forum

I'm using Firefox on Ubuntu, and every time the browser crashes and I reopen it, I get the "Start New Session" or "Restore Previous Session" prompt. I’ve tried both options at different times, but in either case, I find myself logged out of Gmail.

This is quite frustrating, especially considering the number of authentication steps required to log back in (e.g., 2FA, verification prompts, etc.).

It seems like session cookies or state information aren’t being properly preserved or restored after a crash. I had high hopes from Firefox in terms of privacy and stability, but this issue is seriously affecting my workflow.

Has anyone else faced this? Is there a way to ensure that sessions (especially login sessions like Gmail) are preserved after a crash?

Any help or suggestions would be appreciated!

First got a msg box from Firefox that my W10 PC had crashed overnite - and I could report it. My PC was back up & looked normal - but when I accessed Firefox the PC crashed - then I got the above error & blue screen and could do nothing on the PC! I restarted again - as long as I DO NOT START FIREFOX - my PC is fine. Help pls! For what it's worth, I happened to open a lot of tabs in Firefox yesterday. Drivers are up-to-date. Vicki

It appears that I have a zombie Firefox browser running because when I close the browser using the top right 'X' button, the Firefox processes are still running when I check Task Manager.

If I end the Firefox task and reopen Firefox the first attempt seems to be stuck crashing because there's no crash log, but I can see in the task manager there's a crashhelper. A second attempt opens just fine, but the issue with that is my previously opened browsers are gone even with the setting to reopen them is enabled.

I've tried reinstalling, disabling my extensions, and updating Java, but none of these resolve the issue.

When testing our web application, I can consistently get the tab to crash in Firefox (not other browsers). This happens even when running in Troubleshoot mode.

A few of the submitted crashes: bp-f1e47e32-aa7e-4080-880c-34f160250710 bp-622b9363-fa50-4b15-b605-87c3e0250702

Can anyone tell what is causing it to crash, and if we can do something to fix it?

I can't access "settings." When I click "Settings" a faint shadow around the edges of my screen appears, but the actual page does not load. Sometimes, Firefox itself won't open for several days so I've had to start using an alternate browser when this happens. Is this a known issue?

Firefox tabs keep crashing randomly and sometimes the entire thing just crashes and the browser has to be restarted completely. I' have already tried: Updating Firefox Completely reinstalling firefox after I removed all App Data of it. Updated all the drivers that were possible to update. Installed newer codecs (H265)

Nothing so far worked to solve this issue.

I believe this problem is caused by a false crash recovery loop, every time I open firefox it'll close again and then give me an annoying red striped address bar. I'm sure its not my extensions because I only have Ublock Origin installed.

Trying to download updates from Intel.com and as soon as I click the download button, Firefox just locks up and won't allow me to do anything. I have to basically shut down firfox through task manager to get the browser to work again. I have 139.04 which is the latest update for Firefox

A message to Mozilla if this is a bug how about fixing the problems that some people are having instead of consintration on implementing AI into Firefox as I want a browser that doesn't and isn't link to AI as many other people do as well as some if not most of us are sick to ther back teeth with everything having AI installed with in the programs.

Firefox keeps crashing my computer while playing graphics-intensive games, yet with Firefox off they function perfectly. This seems to be still an issue since 2015. It'll be a shame to switch browsers since i been using this since it was called Netscape 2

bp-99a3af9e-c74e-4a75-9564-ae4050250703

this is the latest crash report. had 19 crashes in about 1 hour. i have noticed when i put stress on my pc IE playing a game the crashes are less. i have 64g ram i9 14900k cpu. disabled all extenstions have uninstalled and reinstalled firefox but nothing im doing seems to help.

any help would be great.

The crashing is soo repeated- that even on an individual web page- it can crash over & over; a page won't remain open more than a moment (literally) & can crash again & again.

This's across different websites.

Just started like this week.

Any suggestions? Can Mozilla fix this??

Thanks!

Hi,

Firefox version: 139.0.4 (64-bit) OS: Windows 11

I have been having issues where Firefox tab will just crash out for no reason it appears and it happens at random times and once the tab start to crash, and I restore it, it will crash again and again. The only way tog et out of the loop is to restart Firefox.

I have tried: Refreshing/Reset, Clearing Cache and History removing all themes, disabling extensions, disabling my anti virus. Turning off hardware acceleration didn't make any different.

I currently have 2 extensions enabled: uBlock Origin 1.64.0 and Bitwarden Password Manager 2025.5.0

In the about:Crashes I have reported them all and they seem to have the same type of reasons in the Raw data/Minidump which are: EXCEPTION_ACCESS_VIOLATION_WRITE EXCEPTION_ACCESS_VIOLATION_READ

Any help as to what to try next?
