No matter what I change in the connection settings the following pops up on my screen. HELP!!!

Unable to connect

Firefox can’t establish a connection to the server at support.mozilla.org. 

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.

  • Make sure your Internet security software is up-to-date (i.e. you are running the latest version).
