Unfortunately, that crash report is empty. Does the crash happen every time you start Firefox? What if you hold down the option key when starting Firefox? That should start in Firefox Safe Mode. If it doesn't crash then, the cause is probably an extension. See Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems.
Yes it happens every time and yes it still crashes in safe mode.
Okay, try this: Your personal data is stored in a folder separate from the Firefox app. It's called your "profile folder". You can actually create more than one profile, and if the problem doesn't exist in a second profile, you'll know that the cause of the problem is somewhere in your original profile folder. To start the profile manager, see Profile Manager - Create, remove, or switch Firefox profiles

If that new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.
