Recently I have been working on creating a distribution of Tor which includes a pre-configured browser -- the Tor Browser Bundle. It is intended for being run off an USB flash drive, but will probably also be helpful to users who want an easy-to-setup packaging of Tor.
More information and download links can be found here: http://torbrowser.torproject.org/ The bundle contains Firefox, Tor, Vidalia, Polipo and Torbutton. No installation is needed (just unpack the contents). All the components are automatically started by one double-click. The bundle is new, and contains development versions of Tor, Vidalia and Torbutton, so should be considered a testing release. I do hope it will be useful, and I'd appreciate comments, suggestions, and bug reports. Thanks, Steven. -- w: http://www.cl.cam.ac.uk/users/sjm217/
