Firefox won't open, quit, force quit or finder quit. Help!
I can't open a new window. I can't select preferences. I can't shut it down even when I try to force quit. Going to the finder and shutting down does not work. This prevents me from shutting down my computer.

Can you start Firefox in Safe Mode by holding down the Shift/Options key?
Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.
- Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
- Do NOT click the Reset button on the Safe Mode start window

Poke around safe web sites. Are there any problems?
Then restart.
