The Tor Project has proudly announced the release and immediate availability for download of the first stable Tor Browser 5.5 web browser for all supported operating systems, including GNU/Linux, Mac OS X, and Microsoft Windows.

There are numerous new features in TOR Browser 5.5, and among some of the most important ones, we can mention the implementation of a defense protocol against font enumeration attacks, and further improvements to the keyboard fingerprinting defense. Other highlights include the ability to isolate Shared Workers to the first-party domain, the addition of a Japanese locale, and about:tor appearance polishing.

"On the privacy front we finally provide a defense against font enumeration attacks which we developed over the last weeks and months. While there is still room for improvement, it closes an important gap in our fingerprinting defenses. Additionally, we isolate Shared Workers to the first-party domain now and further improved our keyboard fingerprinting defense," reads the announcement.

Powered by Tor 0.2.7.8

Based on the ESR (Extended Support Release) version of the Mozilla Firefox 38.6.0 web browser, Tor Browser 5.5 updates many of its core components to their latest versions available at the moment of writing this article, such as Tor Launcher to 0.2.7.8, Torbutton to 1.9.4.3, NoScript to 2.9.0.2, and libevent 2.0.22. Of course, over 30 bugs have been squashed, some platform specific, which you can see in the changelog below.
