No screen, so I can't start in safe mode; won't quit; won't force quit; won't let me uninstall the app; won't allow the computer to restart because the app is supposedly "open"

Rebooting the computer should close everything.

Start Firefox in Safe Mode {web Link} by holding down the <Shift (Mac Options) > key, and then starting Firefox. Is the problem still there?

While you are in safe mode;

Type about:preferences#advanced<Enter> in the address bar.

Under Advanced, Select General. Look for and turn off Use Hardware Acceleration.

Poke around safe web sites. Are there any problems?
