Tor Browser 7.0a1 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 7.0a1 is the first alpha in the 7.0 series. Apart from the usual Firefox update (to 45.7.0 ESR) it contains the first alpha in the tor 0.3.0 series (0.3.0.1-alpha) and an updated HTTPS-Everywhere (5.2.9) + NoScript (2.9.5.3).

Tor Browser 7.0a1 is the first alpha allowing Linux users to test Snowflake, a new WebRTC-based pluggable transport. Additionally, we include bug fixes both to our sandboxing solutions for Linux (sandboxed-tor-browser 0.0.3) and macOS. For Windows users we plugged a timezone leak that got introduced by enabling ICU in Firefox when switching to ESR 45.
