Tor Browser 8.0.4

Tor Browser

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.

Tor Browser 8.0.4 release notes:

This release features important security updates to Firefox.

Tor Browser 8.0.4 contains updates to Tor (, OpenSSL (1.0.2q) and other bundle components. Additionally, a number of patches from the alpha series has been backported where they got some baking time. The most important ones are:

  • a defense against protocol handler enumeration which should enhance our fingerprinting resistance,
  • enabling Stylo for macOS users by bypassing a reproducibility issue caused by Rust compilation and
  • setting back the sandboxing level to 5 on Windows (the Firefox default), after working around some Tor Launcher interference causing a broken Tor Browser experience.
