Try Tor. Tor is the untraceable, untrackable answer to all internet needs. It bounces you off a hundred satellites and proxies, keeping all users anonymous.

Unfortunately, the TOR browser is a modification of Firefox. If you want to avoid Mozilla, use a different browser with TOR, and be a bit more careful.
The guy running Silk Road got busted anyway...
