1) Wait until it fully connects to Tor
2) Run this command in command shell (replace firstname.lastname@example.org
with actual username and hostname of your SSH account):
$ torify ssh -D 8080 email@example.com
3) It will asks for ssh password. Enter it.
4) Open browser and put these proxy settings: Type: SOCKS5, Host: localhost, Port:8080
The traffic will flow like this: Browser -> localhost:8080 -> tor -> tor exit node -> ssh.host -> target website.
Target website will see only ssh.host's IP, and ssh.host will see Tor exit node's IP. Beware ssh.host can still de-anon you by your payment/register information. (or how did you get this ssh account?)
