It just stopped booting up when I click on the icon. I have also uninstalled it and reinstalled a new copy but it just won't respond at all. I have run the anti virus program and resolved any issues there but even with a new installation, it won't boot up.

What is your computer system and 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

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