It would appear that the corrupted script files are sessionstore.js or prefs.js. these i found in Application Data/Mozilla/Firefox/Profiles/2xewu6aw.default folder

You may also have a lock file in your default folder after a crash. Then Firefox will say "already running". If you delete the lock file then Firefox should start again.

Firefox is already running but is not responding
