What is Tor Browser?
"The Tor software protects you by bouncing your communications around a distributed network of relays run by volunteers all around the world: it prevents somebody watching your Internet connection from learning what sites you visit, it prevents the sites you visit from learning your physical location, and it lets you access sites which are blocked.
The Tor Browser lets you use Tor on Windows, Mac OS X, or Linux without needing to install any software. It can run off a USB flash drive, comes with a pre-configured web browser to protect your anonymity, and is self-contained (portable)."
There's so much stupid in this discussion that it just gave me a headache. Most of you who replied need to take off the tinfoil hats, because tinfoil actually concentrates the microwaves, and most of the AC replies exhibit behavior consistent with having their brains zapped for a little too long.
To stay somewhat on topic: The Tor Browser is a fork of Firefox ESR, yes, but they do a bunch of hardening-related patching. Even if you're smart enough to set up a computer to transparently route all of its traffic over Tor, you should use the Tor Browser anyway. It will take a little bit of extra configuration so that you don't have a tor-over-tor situation, but it really is the best tool for the job. Maybe that's why we have so many ACs parroting law enforcement talking points...
