Firefox updated yesterday and ever since then it will not open at all. I am running the latest macOS on a MacBook Air. It just bounces on the Dock once then doesn't open at all. I have tried uninstalling and reinstalling AND I even tried to downgrade back to 70.0.1 and it STILL didn't work. It won't even open in Safe Mode.

  • Make sure your Internet security software is up-to-date (i.e. you are running the latest version).
  • Remove Firefox from your program's list of trusted or recognized programs. For detailed instructions, see

It only works if I run it off the downloaded disk drive. Also I am running it on a Mac and my firewall is turned off. I have no internet security software.
