Firefox is dead !!

Hi SuSE people, Fired up Firefox and went to a website that said it needed a flash plug-in. OK , let it download it. Plugin downloads and Firefox dies. Try to restart Firefox - nothing - just tries to restart and then just dies and never opens. Restart X -nope ! Reboot - nope! What is this ????? How can a plugin kill an app like Firefox ??? Please help !!!! Bob S.
