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.

HI petersmith101, There were no reports of the system being down last night, however, if you clear the cache of the site by going to the about:permissions page you can search for the site, click "Forget this Site" and that should do it.
