Tor Browser is a free web browser based on Mozilla Firefox and the Tor anonymization network. Tor is an acronym for The Onion Router, a decentralized anonymizing computer network based on specific servers called "nodes" - Source: Wikipedia
The application is aimed at people who want to improve their security on the Internet, helping them to remain anonymous when browsing the web or using instant messaging or other applications using the TCP protocol.
It protects you by bouncing your communications off a network of relays, managed by volunteers from all over the world, working to keep the Internet open, public and accessible.
It prevents a third party, a government, from scrutinizing your Internet connection, observing the sites you visit, preventing sites from knowing your physical location, and even allowing access to blocked sites, censored for one reason or another. Available for Windows, Mac OS X or Linux and portable. The price? A concession on display speed.
