Sorry to hear about the crashes. That crash signature is strongly linked to ATI RADEON graphics. I don't know whether you have checked for updates to the driver software, but if you haven't checked recently, please see this article: [[Upgrade your graphics drivers to use hardware acceleration and WebGL]]. Do you have crash report IDs from when Firefox was in Safe Mode, in case they are different? Hardware acceleration is disabled in Safe Mode, which usually bypasses most issues with graphics drivers. But not all...
