Shouldn't web be port 80?

I know that port 80 is used for web browsing but ever since I installed Proxomitron and PeerGuardian I'm noticing something. With Proxomitron on, why does it use a local port that is not 80 when trying to connect to a website? Is this normal? When outside trying to connect mine why doesn't it use port 80?

And no, I don't see port 8080 either.

 

Port 80 would be the remote port your browser is connecting to when you go to a website.
The proxomitron is listening on port 8080 on your localhost for connections, so the browser would connect to port 8080 and proxo is then connecting to the remote server on port 80, this is what i see happening on my system using the firewall-log.
Aswell your browser as the proxo will use a local source ports of course.
