I was having a problem with a piece of software and was advised to clear my browser history. I cleared ALL history and now Firefox will not load. I have downloaded/installed the latest version, and it still won't load. When I click an icon that should start Firefox, I get the little timeclock for a few seconds - then it stops and nothing happens. I am on Windows 8.1. Any ideas how to make it work ?? THANKS !!

What told you to clear the history?

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

Configure firewalls so that Firefox can access the Internet. {web link}

Do you see any error messages?

Did you delete the Firefox profile folder?

  • C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Profiles\<profile>\

Try to start Firefox in Safe Mode by holding down the Shift (Mac: Options) key to see if that helps.

Create a new profile as a test to check if your current profile is causing the problem.

See "Creating a profile":

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.
