Tor Browser allows a user to browse in safety and anonymity. It blocks trackers, defends against surveillance, resists fingerprinting and includes multi-layered encryption. It automatically clears any cookies and browsing history and blocks browser plugins such as Flash, RealPlayer, QuickTime, and others that can be manipulated into revealing your IP address. Tor Browser already comes with HTTPS Everywhere, NoScript, and other patches to protect your privacy and security.
The browser is free.
