Download Tor Browser 5.0.6

Version 5.0.6 of Tor Browser has been released two days after version 5.0.5. Tor stands for The Onion Router and is a network that can be used to surf the Internet fairly anonymously. All users’ tcp traffic is routed through various Tor routers, after which it is virtually impossible for the recipient to trace 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. Based on Firefox Extended Support Release version 38.5, this release contains the following changes and improvements:

Tor Browser 5.0.6 has been released
This release features important security updates to Firefox which we missed in our update to Tor Browser 5.0.5. We are sorry for this inconvenience. This change is the only one in the changelog since 5.0.5:

• Bug 17877: Tor Browser 5.0.5 is using the wrong Mozilla build tag

This release features important security updates to Firefox. Additionally, we included updated versions for Tor (0.2.7.6), OpenSSL (1.0.1q), NoScript (2.7) and HTTPS-Everywhere (5.1.1). Moreover, we fixed an annoying bug in our circuit display (circuits weren’t visible sometimes) and improved our fingerprinting defense against MIME type enumeration.

Tor Browser 5.0.5 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.
