New Tor Browser 4.0.4 Released

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 4.0.4 is based on Firefox ESR 31.5.0, which features important security updates to Firefox. Additionally, it contains updates to NoScript, HTTPS-Everywhere, and OpenSSL (none of the OpenSSL advisories since OpenSSL 1.0.1i have affected Tor, but we decided to update to the latest 1.0.1 release anyway).

Note: The individual bundles of the stable series are signed by one of the subkeys of the Tor Browser Developers signing key from now on, too. You can find its fingerprint on the Signing Keys page. It is:
