Tor Browser 4.5a4 is released
The Tor Browser team is proud to announce the release of the fourth alpha of the 4.5 series of Tor Browser. The release is available from the extended downloads page and also from our distribution directory.
Tor Browser 4.5a4 is based on Firefox ESR 31.5.0, which features important security updates to Firefox. Moreover, this release includes an updated Tor, 0.2.6.3-alpha, and switches Scramblesuit and obfs3 bridge support to a new golang-based implementation. We are especially interested in hearing any issues with using obfs3, obfs4, and Scramblesuit in this release.
The release also features several improvements to usability, following the results of the usability sprint at the end of last month. In particular, the Torbutton onion menu and related preference windows have been overhauled to provide more simplicity and more focus. The onion menu now features a much requested "New Circuit for this site" option, and the security and privacy settings window have been simplified. For censored users, the first run configuration wizard was also improved to present the choice of Pluggable Transport before the local proxy information, in an effort to avoid confusion between Pluggable Transports and local proxies. As can be seen from the changelog below, the release contains several other usability tweaks and enhancements as well.
