Thank you for the report. There is not very much information about the cause of this crash. Did you test in Windows Safe Mode or Firefox's Safe Mode? In Firefox's Safe Mode, Firefox temporarily deactivates extensions, hardware acceleration, and some other advanced features to help you assess whether these are causing the problem. If you have not already tried that: Hold down the Shift key when starting Firefox. A small dialog should appear. Click "Start in Safe Mode" (''not'' Refresh). Any improvement?
