Download Tor Browser Bundle 4.0.6

Version 4.0.6 of the Tor Browser Bundle has been released. Tor stands for The Onion Router and is a network that can be used to surf the internet anonymously. All users’ tcp traffic is routed through different Tor routers, after which it is no longer possible for the recipient to determine who the original sender was. This information is still present within the Tor network, so that answers – of course also via the system of routers – eventually arrive at the right place. The release notes for this release can be found below.

Tor Browser 4.0.6 has been released
Tor Browser 4.0.6 is based on Firefox ESR 31.6.0, which features important security updates to firefox.

Note to MacOS users: This is the last planned release that will run on 32 bit MacOS versions. Users of Mac OS 10.8 (Mountain Lion) and newer versions will be automatically updated to the 64 bit Tor Browser 4.5 when it is stabilized in April, and we expect this transition to be smooth for those users. However, the update process for 10.6 and 10.7 users will unfortunately not be automatic. For more details, see the original end of life blog post.

Here is the changelog since 4.0.5:

• Update Firefox to 31.6.0esr
• Update meek to 0.16
• Update OpenSSL to 1.0.1m
