Sun May 30, 2010
i was having some problems viewing my facebook profile last night
i was at work and i tried several times to access my profile but the page would not load. so i thot. ok, ill just open the port number.
after researching, i found out that facebook uses port 80, and my http port was open
so what else could it be? it was my parental control that was blocking it
