Firefox 3.6 is not connecting to the internet. It's on my allow list on my firewall and I have to use IE for now! This has happened to a few other people I know. Help? :/

This is the message I get when I open Firefox:

Unable to connect


Firefox can't establish a connection to the server at en-gb.start3.mozilla.com.


   *   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.

Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox.
