Tor Browser 6.0a5-hardened is released

A new hardened Tor Browser release is available. It can be found in the 6.0a5-hardened distribution directory and on the download page for hardened builds.

This release features important security updates to Firefox.

It contains a bunch of noteworthy changes. We switched the browser to Firefox ESR 45 and rebased our old patches/wrote new ones where necessary. We also ship a new Tor alpha version,, which makes meek usable again and contains a number of other improvements/stability fixes.

Note: There is no incremental update from 6.0a3-hardened available due to bug 17858. The internal updater should work, though, doing a complete update.

Here is the complete changelog since 6.0a4-hardened:
