Firefox does not connect to the internet. Tried several solutions, nothing works. Firefox can't even connect to Mozilla for updates


Firefox no longer connects to internet on my mac, and windows machines, after v18. I've tried several solutions from Mozilla support and nothing works. Firefox can't even connect to Mozilla for updates. Firefox just sits on the default search page and attempts to connect to websites by typing URLs, or by clicking on the links on the default search page don't work.

You could try the following:

  • 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.
