Firefox 146.0.1 crashes every time upon launch, even in troubleshooting mode, with exception code 0xc0000005
Firefox 146.0.1 crashes every time upon launch (basically fails to launch), even in troubleshooting mode, with exception code 0xc0000005. Prior to today, it was working fine. Windows does not show any updates made over the last couple of days. I am on Windows 11 25H2, and I'm current with updates. Chrome works. Edge works. I logged on to the same computer as a different user (different profile folder in the user AppData folder) and Firefox still does not work. I tried to refresh Firefox and that did not resolve the issue. I tried to uninstall and reinstall Firefox and that did not resolve the issue. I tried to run DISM and SCANNOW and that did not resolve the issue. No issues are detected with a virus scan. I am stumped - please help!

laptop, desktop, or DIY? If not DIY, what make and model? What security software besides MS Defender are you running? Windows home or pro? If you're running Windows Pro version, I would test in Windows Sandbox to confirm. https://www.howtogeek.com/399290/how-to-use-windows-10s-new-sandbox-to-safely-test-apps/
You can also boot windows to safe mode with networking to see if you still have the same issue.
It launches in Windows Sandbox. It launches after booting Windows to Safe Mode with Networking. It even launches when I click the link to this case from email. But, it still will not launch in regular Windows mode from the shortcut or from "C:\Program Files\Mozilla Firefox\firefox.exe". I have a Dell Optiplex SFF Plus 7010, running Windows 11 Pro.
We're sorry to hear that your Firefox seems to be crashing when you open it. Please perform the following steps to give us a crash report ID that helps us find out more about the cause of the crash.
- On the keyboard, press [Windows]
+ [R]. This should bring up a Run box that contains a text field.
- In that text field, type %APPDATA% and press Enter. An explorer window should open.
- From that explorer window, double-click on the Mozilla folder, then double-click on Firefox and then on Crash reports. Double-click on submitted.
- Now, you should see a list of files that contain reports. Go to View > Arrange Icons by > Modified to get the most recent files at the top of the window.
- Open the most recent 5 files with a text editor and copy the IDs.
- Paste each ID with bp- into the reply window on the forums.
Thanks in advance!
You can find more information and troubleshooting steps in the Troubleshoot Firefox crashes (closing or quitting unexpectedly) article.
I do not have a Submitted folder in AppData\Roaming\Mozilla\Firefox\Crash Reports.
I do have a file in AppData\Roaming\Mozilla\Firefox\Crash Reports called crash_helper_server.log, and it says "[ERROR crash_helper_server] The crashhelper encountered an error, exiting (error: Generic system error: 109)".
After rebooting, it will no longer launch from the email link, either.
