woke up one morning tried to open Firefox, no luck. restart, tried again no joy. Uninstall and reinstall no luck. Tried for profile manager, got XML Parsing Error: undefined entity etc. Don't want to reset Dell to factory settings - a pain. By the way my access to browser choice also impossible. Using explorer which I don't like to access internet. There is corruption somewhere so I may have no choice.

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, then add it back. For detailed instructions, see

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