Portable Anonymous Firefox + Tor

TorPark is a pre-packaged portable installation of the Firefox browser integrated with the Tor anonymizing onion router. You can download TorPark and extract it to a USB thumb drive. Just run the Torpark.exe file to start a new browser, and run Torkill.exe after you finish to end all associated processes. With this you can turn any computer into a secure connection, and will disguise your IP address by routing your request through the encrypted Tor network.

There is more information about Tor available in the TorFAQ. If you want to help provide anonymous web access you can run a Tor server. Help free the Chinese people from oppressive censorship.
