Firefox Support Forum

I am on Mac OS High Sierra Since about a week literally any Russian website I open just crashes Firefox immediately. I have tried to restart in Safe Mode and clear history - it didn't help. What is happening?! Using Chrome in the meantime (no crash there)

My Mozilla occasionally crashes on various websites but this is rarely a big deal and is usually restored without further problem. However, when trying to access my online banking (Co-operative and Smile) it crashes repeatedly after a few seconds, making these sites unusable. Anyone got any ideas why this specific site is a problem and how to overcome it?

My cookie cache is erased every time firefox closes and I only have Ecosia as an Add on. My security setting was strict but I changed it to standard. This had no effect. I'm not very familiar with Linux so a simple explanation would be appreciated!

Thanks in advance

P.S; The crash reports fail to submit. I don't know if this is related.

Hi guys,

do I assume correctly, that if after-crash update to 89.0 wiped clean my sessionstore-backups folder, I've lost all my 50+ tabs forever? Firefox crashed, I started it and it opened with no tabs, like a new installation. I immediately went to sessionstore-backups folder and found that Firefox wiped it, created new empty recovery.jsonlz4 and recovery.baklz4 files and no other files are there (no, there are no alternative profiles in my Firefox directory).

I tried to recover deleted files using Disk Drill, however they seem to be corrupt, because the History Scrounger is not able to decode them. Does anyone have any other ideas, or is this it and I just have to move on? It was on my work laptop, so recovering the tabs would be extremely helpful and would save me lots of time and possibly some trouble too.

Thank you, Sam

Hi,

My name is Julio. I'm from Brazil and i'm using Ububtu 18.04 LTS OS. After an update/upgrade routine firefox have started to crashing at startup. I've tried almost everything avaible on mozilla's support webpage (https://support.mozilla.org/pt-BR/kb/falhas-do-firefox-solucione-previna-e-obtenha-ajuda#w_peca-ajuda-para-solucionar-esta-falha). I've already removed manually the folder .mozilla (~/.mozilla) and tried a clean install using different ways: ubuntu repository, comand line (sudo apt install firefox), synaptic repository, downloading the firefox-89.0.tar.bz2 file on firefox webpage... and nothing have worked for me. I can't access the troubleshoot mode (the app crashes before that). When i ran firefox on comand line the outcome is:

ExceptionHandler::GenerateDump cloned child 12536 ExceptionHandler::WaitForContinueSignal waiting for continue signal... ExceptionHandler::SendContinueSignalToChild sent continue signal to child Exiting due to channel error. Exiting due to channel error. Exiting due to channel error. Exiting due to channel error. Exiting due to channel error. Exiting due to channel error. Exiting due to channel error. Exiting due to channel error. Exiting due to channel error.

Despite the information avaible on support webpage, i couldn't find a folder ~/.mozilla/firefox/Crash Reports/submitted. I've found just text files: LastCrash and submit.log (and another stuffs).

Follows the content of submit.log file:

[dom 06 jun 2021 23:10:29 -03] Crash report submitted successfully [dom 06 jun 2021 23:13:31 -03] Crash report submitted successfully [dom 06 jun 2021 23:16:23 -03] Crash report submitted successfully

And the content of LastCrash is:

1623033026

Could somebody help me, please?

Hi for a while now, few months Firefox crash like crazy on my PC

Sometimes it would just crash at start, and refused to open Sometimes tab start crashing, and eventually firefox crashes

Common sites where i see the crash happens are cnn.com and nba.com

I usually restart my PC , refresh firefox or reinstall it to get rid of the crashes but this is very tiring , very tiring

I am sure its something on my PC that causing the conflict, because even reinstalling doesnt entirely fix it

But i have no clue what it could be

My firefox is crashing even with the troubleshoot mode I updated the latest version, disabled the extensions and removed cache and still crashing

On my new PC with a fresh and fully up to date installation of Windows 10, Firefox tabs keep crashing for no reason.

Ticking all the boxes they give me in the crashed tab and hitting reload/refresh tab is unlikely to actually fix the tab. I have to hit that button at least 5 times to maybe get the tab working again and even then it's basically a coin-toss whether it actually gets fixed or not.

I have 7 firefox.exe.(number).dmp files with no way to upload them here but if there is an way to do that please let me know so I can provide additional data.

Please help me with this ASAP, I'd rather continue to use Firefox on my new machine than go back to Chrome. Thank you.

Ubuntu 21.04 latest firefox 90. Firefox crashes randomly or each by clicking right mouse button in Bookmarks Menu button any folder/url. Also bookmarks are not visible via the Bookmarks Menu button. about:crashes is Empty

Since yesterday's update on my Windows 7, today I first got error messages on pages I usually visit, my home page and the Google signin page among my Favorites. The browser crashed when I tried to bring up Settings. Subsequently I could not open it again. I just shut down that computer in case repowering it solves the problem later. This is Mac Catalina. Firefox just updated here. I hope on this computer the problem does not surface.

I have two problems with Firefox 90.0.2 (64-bit).

1. Sometimes the program stops responding; sometimes it restarts on its own but sometimes I have to close it.

2. Sometimes when I switch from Firefox to another open program Firefox closes on its own.

Thanks.

Two days ago Firefox randomly started crashing on start up. I click on the icon and the window pops up for a moment and then closes immediately. I get no crash reports. I have tried reinstalling Firefox and deleting the cached data. I have tried running Firefox in Troubleshoot Mode and as an administrator. I have tried restarting my computer and updating my computer. I did not have any addons installed on Firefox and I was using the default theme. Nothing is working.

Any help you may have is greatly appreciated.

I am hoping someone from Firefox Development sees this and that something can be done for those of us who need to have several tabs open simultaneously. I often find myself engaged in research that for convenience requires that I have several tabs open which eventually leads to browser slow down, hanging, and sometimes a crash. Im convinced this is the correct analysis since defragging the ssd fixes it every time. I believe it would be very helpful if Firefox were to add a compressor to its file storage routine, first blush thoughts, possibly one compressed file per tab. When I get into heavy research I find myself defragging sometimes several times in a day, which temporarily fixes the problem. Any chance this can be added, or if anyone knows of a fix to this issue? rgds, j

Instagram crashes on firefox every few days, happens when reading posts or watching stories (no new content is loading during crash). Happens only on firefox, never on other websites. Happen every few days, when I press reload the website after crash, it works temporarily, but it may happen after some days. My network is good enough.

using 91.0 (64bit) firefox, macOS Big Sur 11.5.1, both latest version

tried delete cookies and history, turn off hardware acceleration. I didn't install any extra extensions.

feel sad because i know it would crash again after some days. What can I do?

Tab crashes and complete browser crashes have increased recently on my system. I have tried switching off extensions too, but can't get it to stop. Any help will be appreciated.
