Crashes immediately on start-up. When I click Restart Firefox, it still crashes. When I click Quit and then attempt to restart firefox, it immediately crashes. After Restarting, it still crashes as the first application started.

Chosen solution

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" in case there are still problems.

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.
