If you have a ssh connection to a remote machine, you can use socks to proxy all your web traffic through that machine.

All you have to do was to write to your personal home desktop .ssh/config file:

Host myhost
   HostName proxyhost.domain.tld
   User myusername
   DynamicForward 20000

then just change mozilla connection params to use 127.0.0.1:20000 as a socks proxy. Then just login to proxyhost via ssh and start browsing the web and all your traffic will go through the ssh socks proxy!
