I've tried 'installing' it for days now. I've removed (sudo apt-get purge firefox) the FF browser that's included with Mint and tried installing Nightly (sudo apt-get install firefox) but I keep getting server errors.
I've read forum post after forum post, I've watched video tutorials on how to install tar.bz2 files but cannot get Nightly up and running. I HAVE been able to open it but when I close the browser I have to sift through all the extracted files and open it that way.
Tor is another program. I get confirmation it was successfully installed but can't get it working. When I click to start Tor Browser it opens Gedit.
Also.. Using Mint 13 Cinnamon.
