Sorry to hear about the crashes. The easiest way to provide crash data is to give us links to the reports you've submitted through the Mozilla Crash Reporter. Has that been popping up? If so, please check the support article "[[Firefox crashes - asking for support]]" for steps to get those crash report IDs from the about:crashes page, and then post some of the recent ones here. If you are getting a different crash dialog, such as the general Windows one, Firefox won't have detailed data to assist us. In that case, could you test in Firefox's Safe Mode? That temporarily deactivates extensions, hardware acceleration, and some other advanced features of Firefox that might make it more prone to crashing on some systems. ''If Firefox is not running:'' Hold down the Shift key when starting Firefox. ''If Firefox is running:'' You can restart Firefox in Safe Mode using either: * "3-bar" menu button > "?" button > Restart with Add-ons Disabled * Help menu > Restart with Add-ons Disabled and OK the restart. ''Both scenarios:'' A small dialog should appear. Click "Start in Safe Mode" (''not'' Refresh). Any less crashy?
