since last update, firefox will not start even after repeated attempts. It is apparently open as i cannot delete it from the laptop untill I restart laptop. I am running Windows 7 and i run Thunderbird successfully on my machine. I am forced to use IE to get onto the internet.

Does Firefox not start in Safe Mode?

  • Click the Windows logo orb on the taskbar to bring up the Start Menu.
  • In the search box, type firefox.exe -safe-mode and press Enter.
  • If the little Firefox Safe Mode window pops up, click the Start in Safe Mode button.

If Firefox doesn't start in Safe Mode, does the profile manager start? If yes, create a new profile and try starting Firefox in that profile.

Profile Manager - Create, remove or switch Firefox profiles
