If you download switchproxy, then it works well with tor

Tor is a program that bounces all your connections from your browser or any program through a network of proxy servers, it's almost totally anonymous and quite fast as well compared to some proxys, and unlike most proxy servers where the owner can easily view what your doing, steal passwords and stuff, the people running tor proxies have no access at all to information passing through, because of some encryption system it uses, so it's much more secure, reliable and anonymous that most proxy servers.
