Hi, the crash seems as if it may be caused by your NVIDIA graphics drivers, so perhaps you could try updating or turning off hardware acceleration. More - Upgrade your graphics drivers to use hardware acceleration and WebGL.

Do the crashes also happen with the current release (40.0.2)?

Create a new profile as a test to check if your current profile is causing the problem.

See "Creating a profile":

• https://support.mozilla.org/kb/profile-manager-create-and-remove-firefox-profiles
• http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Profile_issues

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.
