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.

the crash reports have been submitted 748057a7-6757-6eb2-955e-9602f9e91008

is there anything else I can do to get this looked into/resolved?

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!

I'm trying to use Booking.com to pay online for a holiday and Firefox keeps crashing as soon as I press confirm payment. Have tried several times using 2 different cards. What can I do?

I get the message: We're Sorry Firfox had a problem and crashed. We'll try to restore your tabs and windows. To help us diagnose and fix this problem, you can send us a crash report. I sent the crash report multiple times.

I added a screenshot of my MacBook Air info.

YouTube Seiten crashing after a few seconds with Firefox Nightly from 23.05.2026. The build from 22.05.2026 did not have this problem. Right now i did a rollback to the last build to fix this.

I am running Firefox 151.0.4 on a Win 11 (25H2) AMD Ryzen 5, 32 GB ram. Every time I close Firefox, it generates a crash report. That takes several minutes during which I can't start a new Firefox window. The crash report says the report was submitted successfully but when I look in about:crashes the reports shows they need to be submitted.

I ran in troubleshoot mode and disabled all plugins and did not see any extensions listed. I restarted and it still crashes. Firefox seems to run fine. But the crashes when it closes are annoying and disruptive.

here are the first few lines of a recent crash report: Firefox 147.0.1 Crash Report [@ shutdownhang | mozilla::SpinEventLoopUntil | nsThreadPool::ShutdownWithTimeout ]

I’m currently facing a very frustrating issue with Firefox. I have been using Firefox for many years, and it is my favorite and most comfortable web browser for my day-to-day work. I rely on it heavily as all my bookmarks and other important details are saved there.

However, over the past few weeks, Firefox has been crashing more than 10 times a day. I have already tried all the troubleshooting steps available in the forums and through AI support, but none of them have resolved the issue. I also tried installing and using the Firefox Beta version, but the problem still persists.

In our environment, other users and devices are not experiencing this issue, so it does not appear to be related to internal firewall or antivirus restrictions.

Could you please help me troubleshoot this issue? I am attaching the error screen that appears after the crash along with the crash report for you

I wanted to report that Firefox froze or crashed. I could not close it and had to Endtask it. I am running the latest version supposedly on Windows 11. Why did this occur?
