Firefox has crashed now multiple times within a month in following event: - Firefox browser is open (with 1 or more tabs) and Mac OS X 10.6.8 wakes up from sleep - whenever clicking to Firefox to continue browsing, it crashes immediately. Open tabs have never been really heavy pages or something. Simple as it is; If browser is open when waking up the Mac, it'll crash immediately when trying to use it. EDIT: Browser was updated the same day question was posted::.
