Download the latest Tor browser:
https://www.torproject.org/download/download-easy.html.en
Right click on the archive and 'extract here'
Right click on the Tor browser folder and 'open in terminal'
Type sh start-tor-browser on the command line
and you are good to go!
Caveat: I've encountered issues with running Tor browser from time to time in
that the browser won't open. Closing the terminal window and trying again
works most of the time. Occasionally, after 3-4 tries, I will be forced to
open in safe mode. Saving the bookmarks in a separate file and extracting the
folder again (import the bookmarks) will get you going. I've reported the
issue (since the past 3-4 versions of the browser), but it still happens.
Having said that, I use Tor browser almost exclusively. Works great! (most of
the time)
