Download Tor Browser 6.0.7

Version 6.0.7 of Tor Browser has been released. 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 receiver 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. This release is based on the Extended Support Release of Firefox version 45.5.1 and should therefore fix the security problem that has been in the news in recent days.

Tor Browser 6.0.7 is now available

This release features an important security update to Firefox and contains, in addition to that, an update to NoScript (2.9.5.2).

The security flaw responsible for this urgent release is already actively exploited on Windows systems. Even though there is currently, to the best of our knowledge, no similar exploit for OS X or Linux users available the underlying bug affects those platforms as well. Thus we strongly recommend that all users apply the update to their Tor Browser immediately. A restart is required for it to take effect.

Tor Browser users who had set their security slider to “High” are believed to have been safe from this vulnerability.

We will have alpha and hardened Tor Browser updates out shortly. In the meantime, users of these series can mitigate the security flaw in at least two ways:

Here is the full changelog since 6.0.6:
