Firefox repeatedly crashes on my, multiple times a day. I'dc really like to NOT have to change my default browser to Chrome.

What happens is that Firefox freezes, and I get a white bar at the top telling me so. I get a popup box asking if I want to close Firefox or wait for it to respond. Waiting doesn't work, so I always have to close Firefox. When I reopen it, fortunately all m,y open tabs are retained, but it crashes again within minutes or seconds as soon as I click on anything.

There only thing that seems to work is a reboot of my PC. But the respite is short before Firefox crashes again.

I've disabled most plugins, but that hasn't helped. Is there a way to create an event log within Firefox that I can share with someone at Mozilla to help e debug the issue? It's got to be something local rather than Firefox itself; I can't imagine this is happening to most users.

Since a few weeks I have been encountering an issue where tabs in Firefox would frequently crash. I do have various add-ons installed, however I haven't installed any new ones around the time the issue has been occurring. I've been unable to track down which add-on or if any add-on might be causing this.

Trying to search for this issue all I could come up with is that it might be an issue of a faulty CPU. I have an i9-13900KF which has been known to be part of the Intel generation with serious flaws. However I already installed a BIOS update and applied Intel's recommended settings to undervolt the CPU to prevent any issues. This was well before the Firefox tab crashing issue happened. So I'm not sure if it can really be the issue of a faulty CPU, but I've also had issues of other programs randomly crashing recently (like Discord or Steam).

The tab crash can occur on any website, for example Youtube, Duckduckgo, Protonmail, etc. The crash reason always is either "EXCEPTION_ACCESS_VIOLATION_READ" or just "EXCEPTION_ACCESS_VIOLATION". The crash also most of the time (but not always) occurs when loading the page itself or a video / live stream on it. But not when browsing an already loaded page (for example this forum post page I'm writing right now).

Here are some of the crash reports I've submitted:

EXCEPTION_ACCESS_VIOLATION_READ: https://crash-stats.mozilla.org/report/index/60309ae8-8cad-43ac-8b9b-172b10250815 https://crash-stats.mozilla.org/report/index/fecef0ab-d874-4cb5-990b-e49650250815

Rather rare "EXCEPTION_ACCESS_VIOLATION": https://crash-stats.mozilla.org/report/index/114b26fa-4e10-442c-bbd5-406630250812

Could someone help me narrow down this issue? Can it really be a faulty CPU and I need to trade mine in?

Why is Firefox crashing so often? What changed? Is there something I need to do to prevent his? Once or twice a week or sometimes a day, but It seems to crash when I am just in my Gmail, sometimes 4 or 5 times an hour. Is Chrome a better option?

Firefox crashes every day or so on my home computer. The most common error message is "kmode exception not handled." I've tried the suggested fixes. Nothing helps. The crashes are not being recorded in "about crashes" or in %APPDATA%\Mozilla\Firefox\Crash Reports\. So it seems the crash reporter has to be fixed before the problem causing the crashes can be identified. Firefox does not crash on my office computer and no other program causes my home computer to crash. Thank you.

Hello,

I am experiencing a recurring issue with Firefox on Kali Linux.

Environment:

- OS: Kali Linux (running inside Termux on Android) - Connection: VNC (RealVNC) - Device: Android phone (low RAM) - Desktop: XFCE

Problem: Whenever I open Firefox, tabs frequently crash with the message: “Gah. Your tab just crashed.”

What I already tried:

- Disabled hardware acceleration - Disabled recommended performance settings - Ran Firefox in safe mode - Created a new Firefox profile - Lowered VNC resolution - Restarted the system

The problem still persists.

I believe this may be related to graphics rendering or memory limitations under VNC/Termux.

Please advise if there is a workaround or configuration that can prevent this crash.

Thank you for your support.

When I press a hotkey that involves Ctrl (ie. opening a new Tab via Ctrl+T or closing one via Ctrl+W) Ctrl sometimes remains stuck until I press it again. This will cause issues ie. when I open a new tab and try to type a new address (or search term), and Ctrl causes new hotkeys to be executed.

I've even tried launching firefox with a new profile, and on safe mode (firefox --safe-mode -p <something-else-than-usual>), so no bookmarks, cookies or extensions should be causing this, and it will still happen sometimes. The annoying part is that this seems to be an issue with performance. It happens less-often with the empty profile and safe mode, but it still happens, especially if I had just opened a new page some tab, causing the most minute thing for firefox to process.

The problem is probably not the computer specs either (below my specs). Indeed, from what I can tell, firefox does not even seem to function particularily slow in any case. Just this ctrl being stuck seems to happen.

I have also tried disabling hardware-acceleration (and explicitly enabling it), no effect.

Other interesting facts I've discovered: - This for sure does not happen in other programs and - This does not happen with the Ctrl for all the keybinds within firefox. For example, Ctrl+A (for select all) does not trigger this

From neofetch my setup is OS: Arch Linux x86_64 Host: MS-7C56 1.0 Kernel: 6.12.8-arch1-1 Uptime: 2 hours, 10 mins Packages: 2370 (pacman), 7 (flatpak) Shell: zsh 5.9 Resolution: 3840x2160 DE: labwc:wlroots WM: sway Terminal: alacritty CPU: AMD Ryzen 9 5900X (24) @ 4.951GHz GPU: AMD ATI Radeon RX 7900 XT/7900 XTX/7900 GRE/7900M Memory: 5531MiB / 32015MiB

(I have no idea why it's reporting that I'm using Sway, I'm most certainly only using labwc, maybe labwc just reports sway for some programs for compatibility) I've installed firefox from pacman, and my current version is firefox 134.0.1-1

And finally firefox --full-version Mozilla Firefox 134.0.1 20250113214611 20250113214611

I'm not sure what else I could share at this point

I GOT TIRED OF FREQUENT FIREFOX CRASHES (C0000005) IN BOTH THE 64-BIT AND 32-BIT DESKTOP VERSIONS. I HAVE BEEN USING THE 64-BIT VERSION IN WINDOWS 11 (I HAVE A HIGH-END SAGER LAPTOP WITH 32GB RAM. I INSTALLED THE FREQUENT FIREFOX UPDATES BUT THE PROBLEN PERSISTED EVER SINCE VERSIONS 42X WERE RELEASED. I TRIED THE 32-BIT VERSION BUT THE PROBLEM PERSISTED. FINALLED, I TRIED THE DEVELOPER VERSION: NO MORE CRASHES! I READ THE RESPONSES FROM YOUR CLUELESS STAFF TO OTHER CUSTOMERS WITH THE SAME TROUBLE. THIS IS NOT A WINDOWS ERROR; THIS IS A FIREFOX APPLICATION ERROR. MAYBE SOME OF YOUR FIREFOX DEVELOPER CODERS SHOULD ASSIST THE 32-BIT AND 64-BIT DEVELOPERS. OR, DUMP THE VERSION 4X CODE AND BUILD ON THE MORE STABLE 39X CODE. ALSO, DON'T BLAME WINDOWS FOR FIREFOX APPLICATION ERRORS. AND...NEVER SUGGEST A WINDOWS REINSTALL FOR FIREFOX ERRORS!!!

I have tried over several days to uninstall and reinstall Firefox to avoid tabs constantly crashing. While I've done this and multiple shut downs and restarts it continues to crash and can't figure out why. Please help.

Bonjour, Voilà, depuis une mise à jour de Windows 11 la kb 5054979 et la kb 5055523 fêtent ensemble j'arrive à accéder à Firefox à l'aide de la souris mais dès que je tape au clavier Firefox plante. J'ai essayer la mise à jour des pilotes du clavier croyant à un problème de drivers mais il est à jour. J'ai désinstallé les mises à jour mais rien n'y fait J'aimerai savoir d’où peu provenir le problème ?. Firefox envoie bien des infos sur le plantage et essaye de remettre les onglets mais le problème reste le même. merci pour votre aide ? Je n'ai rien trouvé correspondant à mon problème dans les articles d'aide

For the very first time, today I got the following, "Gah. Your tab just crashed." and it now happens every time. What's up? Is this a Mozilla problem? Should I be moving on to a new browser? Help!

I recently swapped to firefox and have had issues with my tabs crashing. There are days where a tab will repeatedly crash, or not at all. It always crashes on 1 tab. I've tried most of the suggested solutions, profiles change, addon troubleshooting, hardware acceleration, updating/reinstalling. Currently on windows 11.

We are experiencing an ongoing issue with Firefox that persists even after performing the following troubleshooting steps: - Uninstalled Firefox completely. - Removed all browser add-ons and extensions. - Reinstalled the latest version of Firefox. Despite these steps, the issue still occurs: Browser crashes, pages not loading, extension not working. Additional Information: - Operating System: Windows 11 Pro - Firefox Version: 145.0.1 - Error Message:

We would appreciate guidance on resolving this problem, as standard troubleshooting has not resolved it.

Thank you in advance for your assistance. Kind regards, Edward

A user I am servicing uses Firefox every day. They are on Windows 11. Every afternoon (sometimes at other times), Firefox stops working and loses its internet connection (everything else on their computer continues to be connected).  When they close and restart Firefox to reconnect, it then tells me the user that they are using an old profile and need to create a new one.  They're able to re-log into their Firefox account, which eventually resyncs all their data, but they then have to re-sign into everything, which is a major inconvenience.  The only workaround the I have found is to reinstall Firefox, ever time this happens which then allows the user to use all their settings until they have to repeat the process the next day (i.e., everything remains signed in and/or logging back in is easier than described above).

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.

Hi there, I'm wondering why Firefox is crashing tabs like crazy for me the last few days. Chat Gpt reckons these screenshots indicate a problem with the JavaScript Engine. I'm looking for expert help to differentiate the cause so I can be sure my hardware isn't damaged. Scrolling fb or youtube , even using chat gpt and firefox just throws me a crashed tab. I have uploaded the reports that chat gpt has reviewed to ensure it is being accurate.

I'm mainly looking to find out so I can rule out if there are problems with my hardware .Any help identifying the source of the errors would be greatly appreciated!
