Through extensive troubleshooting, I am unable to get firefox to open at all.
I've done a full uninstall, cleaned all user directories, program files / x86, program data, appdata roaming and local, etc. I used the Microsoft uninstaller and even Revo Uninstaller to remove everything related to Firefox, did a restart and reinstall of the latest one and it still won't launch.
Firefox was previously working until a reboot occurred and now it won't launch.
Firefox 32 bit seems to work when installed, and running Firefox as an admin previously worked but no it no longer does.
I looked at the following articles: - https://support.mozilla.org/en-US/kb/firefox-wont-start-find-solutions - https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles - https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles#w_start-the-profile-manager-when-firefox-is-closed
There's no malware on this machine (business EDR on it, even disabled it as a test and it still didn't open).
I was able to launch the profile manager but now I am unable to as the processes launch in task manager and then within 5 seconds they close.
Firefox is not running in the background for any user (I'm the only one logged in after a reboot as well)
I'm unable to open in troubleshoot mode either. Tried run as and admin cmd "C:\Program Files\Mozilla Firefox\firefox.exe" -safe-mode
Ran SFC / scannow / DISM restore health commands as well and both came back fine / no integrity violations
