Protect your privacy. Defend yourself against network surveillance and traffic analysis.
Tor is a network of virtual tunnels that allows people and groups to improve their privacy and security on the Internet. The Tor software protects you by bouncing your communications around a distributed network of relays run by volunteers all around the world: it prevents somebody from watching your Internet connection and learning what sites you visit, it prevents the sites you visit from learning your physical location, and it lets you access sites which are blocked.
The Tor Browser Bundle 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.
This version updates Firefox to 78.11esr. In addition, Tor Browser 10.0.17 updates NoScript to 11.2.8, HTTPS Everywhere to 2021.4.15, and Tor to 0.4.5.8. This version includes important security updates to Firefox for Desktop.
Tor Browser will stop supporting version 2 onion services later this year. Please see the previously published deprecation timeline. Migrate your services and update your bookmarks to version 3 onion services as soon as possible.
