There's no rule to block the port 80 in the advanced rules set I think. So you need to create one if needed, and you put it "at the top" of the list if you wish.
That rule is really to prevent EDexter, spyblocker and similar apps to send out info, which they shouldn't in the first place
BTW, That site is a good place to learn about rules http://itsec.commontology.de/firewalls/lns/lns-rules.html
