Your company block these for a reason and you should not be visiting.

With that said:

You would have to this using your ~/.ssh/config and specifically set up a tunnel to each individual site.

A shameless plug for my own tutorial may hlep you:

Using something like this:
Code:
# connect to google
Local Forward 1024 www.google.com:80
typing localhost:1024 into you browser should connect you to google.

But the easiest thing might be to use remote X forwarding (Set by deafult)

EG:

ssh your.home.box
mozilla

This fires up moz. on your local screen, but you are actually surfing from home.
