The latest Tor browser update is for you:

Allowing referrers on per-site basis is a bit harder to do. You still need to use about:config and manually set it, post somewhere and set it back when you are done.

Well, it worth just as much as relying on the browser's user-agent for anti-spam. Nothing. Even the most simple spambots include referrer spoofing. And when referrers are used for "security purpose" (like at Webfaction), I become so confused: I don't know whether I should cry or laugh.
