Tor Browser is a privacy-focused web browser based on Mozilla Firefox that routes all traffic through the Tor anonymity network. It is pre-configured with privacy protections including NoScript, HTTPS-Only mode, and anti-fingerprinting measures.
The browser is typically installed via torbrowser-launcher on Debian/Ubuntu systems or from the official tarball. When installed via the launcher, the command torbrowser-launcher handles downloading, verifying, updating, and starting the browser. From a manual installation, the browser is started using ./start-tor-browser.desktop from the extracted directory.
Tor Browser automatically connects to the Tor network on startup, encrypting traffic through multiple relays to anonymize the user's location and browsing activity. It includes a circuit display showing the relay path and allows requesting new circuits for different exit nodes.

Tor Browser should not be used with other browsers simultaneously for activities requiring anonymity, as this can compromise privacy. Downloading files or enabling plugins may expose your real IP address. Performance is slower than regular browsers due to traffic routing through multiple relays. The browser is designed for anonymity, not just privacy.

Tor Browser was first released by The Tor Project in 2008, initially as a bundle combining Firefox with Tor. It evolved from earlier tools like Torbutton and became the officially recommended way to browse anonymously using Tor. The project continues active development with regular security updates and Firefox ESR rebases.
