Tor Browser 8.0.1 is now available from the Tor Browser Project page and also from our distribution directory.

This release features important security updates to Firefox. Note that we just picked up the necessary patches this time but did not bump the Firefox version to 60.2.1esr as we needed to start building before Mozilla was ready. Thus, users are fine with Tor Browser 8.0.1 even if the Firefox version says 60.2.0esr.

Moreover, Alex Catarineu from Cliqz found a mistake we made that would make it possible to trick a user into installing an unsigned Torbutton extension. Thus, all users are encouraged to update older Tor Browser versions to 8.0.1 and keep in mind that installing third party extensions is potentially dangerous to Tor Browser's privacy guarantees and therefore strongly discouraged.

Tor Browser 8.0.1 is shipping the first stable Tor in the 0.3.4 series (0.3.4.8) which solves an annoying crash bug on older macOS systems (10.9.x).

We found a better solution to our User Agent treatment: on desktop platforms Tor Browser will send a Windows User Agent at the network level now while still allowing to query the unspoofed User Agent with JavaScript. This takes concerns about any server passively logging the User Agent into account while still avoiding broken websites as good as we can. Thanks to everyone who helped with this issue.

Finally, we included a banner for signing up to Tor News which allows anyone to stay up-to-date about things going on in the Tor universe (which is, admittedly, sometimes hard to keep track of).

Known Issues

We already collected a number of unresolved bugs since Tor Browser 7.5.6 and tagged them with our tbb-8.0-issues keyword to keep them on our radar. While we fixed a number of them for the 8.0.1 release, there are still issues remaining. The most important ones are listed below:

WebGL is broken right now.

Accessibility support is broken on Windows. We are considering options to address this issue right now.

Tor Browser 8 is not starting anymore on some older Ubuntu/Mint Linux systems. We still have issues to reproduce this bug but hope we can fix it in the next release.

Tor Browser 8 is not starting anymore on CentOS 6. We have a fix in our upcoming 8.5a2 to give it a bit of testing. Users affected by this bug may resort to that alpha version for now. We plan to backport the patch in the next stable release.

NoScript is not saving per-site permissions anymore. We have a potential patch for this bug in our 8.5a2 release as well and plan to backport it, too, in the next stable release in case no issues with it are found.

Note: The changelog file has an incorrect release date (September 24 instead of September 22).
