Firefox vs Tor Browser

The free, non-profit browser for your desktop and mobile devices. Firefox is created by a global non-profit dedicated to putting individuals in control online. We’ve always designed Firefox to protect and respect your private information. That’s why we’re proud to be voted the Most Trusted Internet Company for Privacy.
Tor Browser
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.
