Every time I start Fire fox an error appears that reads UNABLE TO CONNECT. I believe I accidently hit BLOCK rather then ALLOW. How to I reverse my mistake?

Every time I start Fire fox an error appears that reads......

Firefox can't establish a connection to the server at www.yahoo.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.

A possible cause is security software (firewall) that blocks or restricts Firefox without informing you about that, possibly after detecting changes (update) to the Firefox program.

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.
