have you tried uninstalling the version you are running now, downloading and installing another version and see if it loads? a few days back i faced a strange issue after applying update to version 11 after an extension update. i would double click firefox the screen would show for a second and kept going away. i uninstalled, reinstalled rebooted it wouldnt come back. opened task manager to see if its there in processes. seeing that it was not there i decided to go back to version 10.2. it ran fine, but now im on version 12 currently with no issues.
