Fire fox started a download of some unknown file s half-hour before I got the notification, it hadn't downloaded yet so I tried to cancel it but it wouldn't register, it didn't say can't cancel or anything it just didn't respond so I tried to pause it and it didn't register either so I force stopped it and it went away but my concern is it has no permissions to download anything and it wouldn't even let me see what it was downloading, I checked it for updates and it wasn't an update either, what is fire fox doing any idea?
