I keep receiving a 'not responding' error while using Firefox and have been unable to fix it by refresh, uninstall/reinstall, etc. I don't know what to look for next - and neither does my IT guy who has spent several hours trying to fix it. Any ideas?

Is this your PC at home or office?

Some problems occur 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
