New Release: Tor Browser 8.0.4

Tor Browser 8.0.4 is now available from the Tor Browser Project page and also from our distribution directory .

This release features important security updates to Firefox.

Tor Browser 8.0.4 contains updates to Tor ( 0.3.4.9 ), OpenSSL (1.0.2q) and other bundle components. Additionally, we backported a number of patches from our alpha series 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.

Moreover, we ship an updated donation banner for our year-end donation campaign.
