I’m suddenly unable to open Mozilla Firefox at all on my Windows 11 Pro (version 25H2) Surface Laptop. The browser never launches - every attempt immediately crashes and opens the Firefox Crash Reporter.

I tried uninstalling and reinstalling a fresh copy of Firefox (and removing the old application files, though the original Firefox program folder has 13 .tmp files inside a “tobedeleted” folder that I can’t delete), but the issue persists. When I try to install or uninstall Firefox, I get the same behavior: Firefox never opens, and I end up with multiple instances of the Crash Reporter popping up instantly.

Tried renaming firefox.exe as well to no avail. Chrome and Edge are working fine.

Firefox was working perfectly up until this morning and I'm pretty sure there wasn't a new update today. But now when I open the app a new window will briefly pop up for a fraction of a second and then disappear. Unfortunately this prevents me from accessing troubleshoot mode or crash reports so i can't provide much information on specifics.

I followed the steps here: https://support.mozilla.org/en-US/kb/firefox-keeps-crashing-startup and they haven't worked so far. I tried a clean install and restarting my computer multiple times, but no dice. There also don't seem to be any compatibility issues with the most recent version in the release notes.

I'm trying to install Firefox on my work computer (ARM64 version), but when I do I'm getting the crash report window at the end of the installation process (multiple times in a row), if I try to open the browser (only once), and during the uninstallation process (also multiple times in a row). I've tried a clean reinstall multiple times, including deleting the folders from program files, %APPDATA%, and all registry entries I could find (HKEY_CURRENT_USER>>SOFTWARE, HKEY_LOCAL_MACHINE>>SOFTWARE, HKEY_LOCAL_MACHINE>>SOFTWARE>>WOW6432Node).

I've contacted IT and they don't seem to think anything pre-installed should be affecting this. I'm unable to get a crash ID as I'm unable to even start the browser - all I get is the Firefox crash reporter, immediately. Is someone able to help me figure out why I can't get this working?

I click on Firefox Icon, the icon explodes out then nothing happens. I have also tried clicking on it while pressing the option key so I can go into troubleshoot mode and get the same result. I have not found anything so far that addresses this particular situation.

I was already logged into my firefox account with my iPad. The bookmarks from my computer were synced to the cloud. I am pretty sure, however, that my last session was not synced, that is, I am pretty sure that all the windows I had open on my computer were not synced to the cloud.

What do you suggest to get Firefox going again? Ideally, I would like to bring back the sites I had open on the computer the last time I used Firefox on it. Possible?

thanks

Kevin

Hello, I’m having trouble getting Firefox to work properly on my computer. During installation, the setup process becomes very slow, and once I manage to install it, Firefox hangs or becomes unresponsive within a few seconds after launching.

My system details:

Operating System: Windows 10 64-bit

What I’ve tried so far:

Reinstalling Firefox Running in Safe Mode Clearing profile data Disabling antivirus temporarily

None of these steps solved the problem. There are no specific error messages — the browser just freezes, and I have to close it via Task Manager.

My Surface Laptop 7 w/ SnapDragon Elite's Firefox installation started crashing this morning immediately after rebooting to complete some Windows updates. I have attempted starting Firefox in Maintenance mode, Uninstalled and reinstalled and I still get the crash reporter. Refreshing Firefox at the uninstall process does not fix it.

I'm running Windows 11 Enterprise edition, fully patched w/ Firefox 146.0.

The 4 Windows updates that were installed:

Uninstalled KB5072033 Uninstalled KB5070311 Cannot be uninstalled KB5072641 Cannot be uninstalled KB5071142

Still didn't fix the problem.

These are the recent crash reports:

Crash ID: ⁨bp-8ec5b63c-4408-437c-b9bb-f4d5b0251213⁩ Crash ID: ⁨bp-ce396463-0a75-46b6-8131-33cce0251213⁩ Crash ID: ⁨bp-ea0b59dd-1cee-48da-957e-949120251213⁩ Crash ID: ⁨bp-f9342e01-1a55-4387-af6d-3b8ef0251213⁩

Any help is appreciated!

PLEASE READ UNTIL THE END So, a few months ago I reinstalled Windows on my laptop because I had some bugs. After the OOBE was completed, I set it up and installed Chrome. However, when I tried to log in, the app suddenly force closed and could no longer be opened. So, I switched to Firefox. Everything was running fine. But now (06/26/2025), while I was using Firefox, it suddenly force closed (this is the first time it has force closed on me). I clicked twice on the desktop but it also didn't work, I'm confused about what to do, I absolutely don't want to use Microsoft Edge. When I tried to spam the Firefox icon on the taskbar while opening the task manager, crashhelper.exe suddenly appeared many times, I tried to delete those exe files but it had no effect, so I restored them back to their directory. I'm really confused whether my laptop is broken or if there's a bug in the Windows software? So that's it and thank you.

I downloaded firefox and it worked for about a month. Now when I try to launch it, the screen flashes momentarily as though it were about to pop up, but then it does not actually open a browser window. I have uninstalled and reinstalled firefox more than once, I've tried a simple restart of the computer, and tried multiple different update methods (updated windows). Any suggestions?
