Is it recommended to use Tor (the downloadable browser on the Tor website) - https://tor.eff.org - to "anonymously" be on the Internet? Or are there better programs / websites?
Is the Tor browser, obviously a modified Firefox, portable?
How anonymous is anonymous? I could imagine all of your "personnel" data can be found the same like being not anonymously on the Internet, but it would be more complicated, last longer.
