Hello, when I start Thunderird, it appears for a few seconds and then a window pops up saying that a crash has been detected. I've already tried reinstalling the program, creating new profiles, entering Safe Mode, etc. Restoring an older profile from a backup doesn't help, and the error remains the same.

I tried transferring data from the old profile to the new one (a new, clean profile doesn't cause the error), but unfortunately, the data isn't visible in the program, along with the pgp keys and everything else. Manually editing prefs.js using chatgpt didn't help.

What else can I do?

My GPU is the integrated GPU on the Intel U7-155H CPU. When some AVC videos are played, the browser reacts extremely slow and the video image is glitched and at a really low rate of frame, and the video decoding engine seemed to be 100% occupied as shown in the task manager (normal video playback never occupied so much of it). Seems like AV1 encoded video never triggered the problem. The problem doesn't always happen, but at a rather high frequency. This never happened before I updated the Intel graphics driver from 32.0.101.5972 to 32.0.101.6129. The problem seemed not to happen on other browsers such as Microsoft Edge.

Dear All,

I am using Mozilla under Windows 10 in combiation with Bitdefender Anti-Virus-SW. Mozilla worked quite well with this combination. Since two day, I am not aware of any updates, I am not ablel to lauch Mozilla (no reaction). I deactived Bitdefender and tried also the protected mode for Mozilla (deactivating any add-ins). Unfortunately this had no impact. I could not find any helpful advice in forums. Prior de-installing and re-installing SW I am looking for additional hints.

Best Regards Jochen

When logged into a synched account, my Firefox for iOS has been crashing for 2 days. iOS version 18.7.1. First started when I attempted to send a page from my iMac desktop to my iphone. It didn't send, so I attempted again. Still didn't work. Firefox for iOS started crashing when attempting to open a new tab. Then it progressed to crashing whenever I attempt to open Firefox. I then proceeded to:

• Restart phone
• Dump all cache & cookies etc. in iOS Firefox
• Remove iOS Firefox and install new version

However, whenever I sign back into my synched account, the crashing starts again.

So for now just staying signed out of Firefox for iOS, and it's working fine. Hoping this gets fixed somehow in the future, future, future...

Win 11 and Thunderbird 140 not working and I have tried all the things I found on the internet and none of them work. I have tried cleaning my registry and deleted directories and uninstalled thunderbird re-started and it will still not work.

I guess I have to forget thunderbird. It is a shame.

I have Firefox on two separate computers, a desktop running Win7Prof64bit and a laptop running Win10Pro 64bit. Both Firefox installations crash constantly, ie every 10 - 15 mins. They show the "Gah! Firefox just crashed. Please tell us what you were doing", and the box to return the data to Mozilla. With Restore This Tab at the bottom.

I always send you these reports but in about a year, the problem remains the same. Nothing has improved, I never hear back from you. Two different PCs, two different OSs, constant reports, no improvement. Why do I never hear from you? Why does this problem continue endlessly? I'm wasting my time sending you the reports. You take no notice. If you do, why does the problem continue and why do I never hear from you?

Hi - I'm trying to install Thunderbird on my mac to get away from a google workspace account. I've downloaded it a couple times and it crashes immediately after the login screen. Same thing in Troubleshoot mode. It's a work computer so it might have something installed preventing the desktop app from working. Thanks for any help you can offer.

Hello, Randomly but frequently enough to be annoying, Firefox freezes my entire laptop. I have windows 11. It freezes so badly that I have to hold down the on/off button until it goes off. I looked it up outside of Firefox help and, per suggestions, turned off the hardware accelerator. That seemed to work for a little while but now it's happening again with greater frequency. There doesn't seem to be any exact situation that causes it which makes it very hard to diagnose. But it's enough that I'm thinking of looking for another browser so any help would be greatly appreciated. Thank you!

I've gone through the various troubleshooting options over the last month or so and Firefox is still crashing constantly for me, even in Troubleshooting mode. The tabs crash when I'm using a Google Doc, YouTube, Discord, doesn't matter the site; I've submitted about 20 crash reports this morning alone and failed to submit several more:

Any help on this would be greatly appreciated!

With thunderbird version 140.4.0esr (64-Bit) on Linux functions to print e-mails or pdf documents is no longer working. When trying to print an email or a pdf document thunderbird starts looping and you need to stop thunderbird from outside with a kill command.

I’ve observed a consistent issue across several Android devices using Firefox (latest stable version). When trying to launch or interact with certain modded APK-based games—especially those with unpacked resources or modified DEX structures—Firefox either freezes or crashes unexpectedly.

Interestingly, this behavior doesn’t occur on other browsers like Chrome or Samsung Internet. In fact, some third-party websites seem to handle these APKs with stable performance, suggesting it's not an issue with the APKs themselves but possibly how Firefox handles local server callbacks, file-based intents, or memory allocation under WebView.

I’m wondering if this could be tied to Firefox’s stricter security sandboxing, CSP enforcement, or service worker management?

Are there any logs, flags, or debugging routes I can use to isolate the problem further?

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?

I have been having issues with Firefox since the new update. It will work for 5-10 minutes and then cashes and freezes my Macbook. I then have to restart my entire system. I have always loved using Firefox but lately its more of a pain and have been thinking of changing,

Since updating to version 135 all the tabs crash. I've uninstalled\reinstalled, deleted app data, disabled AV and created a new profile. The only time it works is in troubleshooting mode. I've looked at extensions and plugins and I'm only seeing OpenH264 video codec and Widevine content decryption. I've disabled those but still get the crashed tabs.

I'm also not generating any crash logs.

Firefox crashes randomly during video playback. I've submitted over 10 crash reports. Here's the two latest crash report (which includes my device's hardware information): https://crash-stats.mozilla.org/report/index/81eb1750-1dd0-490d-9eb1-d3c2c0250224 https://crash-stats.mozilla.org/report/index/6682a7f2-836a-4365-938e-c9ab20250224

I'm on Fedora 41 + gnome, but this issue persisted even in Windows 11, which caused BSOD therefore I made the switch to linux (At least in linux it doesn't crash the whole system, only firefox). If you need any additional information let me know. I can run journalctl/dmesg if required.

I've already tried things like restarting in safe mode (troubleshoot mode), refreshing firefox etc. Didn't work.

Thanks in advance!

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
