Tor browser
The Tor browser is the official web browser of the Tor Project. Its design focuses on allowing the user to browse the web with a high level of anonymity.
The Tor browser is primarily a modified Firefox browser. It uses Tor Launcher software to connect to the anonymous Tor network and NoScript and HTTPS Everywhere Firefox extensions to ensure connections are encrypted and no JavaScript is running.
While browsing the Internet with the Tor browser, you can be relatively certain that no identifying information will be passed to the websites you are visiting. Identifying information may include your IP (Internet Protocol) address, or the MAC address of your computer. Versions of the Tor browser are available for the OS (operating system), Windows, and Linux operating systems.
