    We are pleased to announce the second release in our hardened Tor Browser series. The download can be found in the 5.5a5-hardened distribution directory and on the download page for hardened builds.

    This release features important security updates to Firefox.

    Additionally, we included updated versions for Tor (, OpenSSL (1.0.1q) and NoScript (2.7). Moreover, we fixed an annoying bug in our circuit display (circuits weren't visible sometimes), isolated SharedWorkers to the first-party domain and improved our font fingerprinting defense.

    On the usability side we improved the about:tor experience and started to use the bundled changelog to display new features and bug fixes after an update (instead of loading the blog post into a new tab). We'd love to hear feedback about both.

    On the hardening side we are compiling Firefox with -fwrapv now. This is mitigating possible issues with some types of undefined behavior in Mozilla's code.

    Tor Browser 5.5a5-hardened comes with a banner supporting our donations campaign. The banner is visible on the about:tor page and features either Roger Dingledine, Laura Poitras or Cory Doctorow which is chosen randomly.

    Note: There are no incremental updates from 5.5a4-hardened available this time due to a bug we detected while building. The internal updater should work, though, doing a complete update.
