Have been happily using Firefox for years. When I shut down my computer today, I had to force quit Firefox. I'm on a Mac. Once I turned it back on it will do nothing. Have reinstalled the software. When I try to open it I get this message (see attached)

I have tried to Reset Firefox and Start in Safe Mode - neither work. Just spins and has to be forced to quit in Safe Mode. Just spins and has to be Force to quit when I try to Reset it.

Help. I can't live without my Firefox!!!

Some problems occurs when your Internet security program was set to trust the previous version of Firefox, but no longer recognizes your updated version as trusted. Now how to fix the problem: To allow Firefox to connect to the Internet again;

  • 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

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

Under Advanced, Select Network. Look for Configure How Firefox Connects and press the Settings button. Check the settings.
