Gmail is allowable but Yahoo is not. This is the message that pops up:

The proxy server is refusing connections




         Firefox is configured to use a proxy server that is refusing connections.
       



 Check the proxy settings to make sure that they are correct.
 Contact your network administrator to make sure the proxy server is
   working.

You can find the connection settings in Tools > Options > Advanced : Network : Connection

If you do not need to use a proxy to connect to internet then select "No Proxy" if the default "Use the system proxy settings" setting doesn't work.
