Firefox crashes
Cannot start Firefox (even in safe mode). I continue to get a window asking me to quit or restart. I have an option to report the error to Mozilla. I've tried that, but the report is not sent. I've tried restarting Firefox, tried restarting my Mac. Nothing works.

Create a new profile as a test to check if your current profile is causing the problems. See Basic Troubleshooting: Make a new profile
There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins"
If that new profile works then you can transfer some files from the old profile to that new profile (be careful not to copy corrupted files)
