on my dads comp hes been using firefox for a few months and today when he tried to open it up it would do nothing, nothing at all pops up, not even an error. i checked in task manager and each time he tried to open firefox the a new process would start for it so he had like 6 processes for it in task manager. i booted the comp into safe mode and firefox loaded up fine, ive also reinstalled it but still no luck.
