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!

This is due to the SentinelOne security interfering with Firefox.

Thanks! SentinelOne didn't have any reported incidents however shutting down the agent fixed the issue, so I'll work on configuring a working exclusion.

My client reported this problem today and also has SentinelOne and a snapdragon CPU.

I was able to install it and make it work by removing the c:\users\[username]\appdata\local\mozilla and the c:\users\[username]\appdata\roaming\mozilla folders along with the folders in c:\program files\mozilla and c:\programdata\mozilla folders.

I then used the firefox 146 msi installer.

I probably didn't need to remove all those folders but that 'shotgun' approach worked.
