In September the Tor Browser team made three releases: Tor Browser
7.0.5, 7.0.6, and 7.5a5.
Tor Browser 7.0.5 fixed an incompatibility of HTTPS-Everywhere with
higher security slider levels in Tor Browser. In fact, it made Tor
Browser compatible with any WebExtension not just that one.
7.0.6 and 7.5a5 picked up new Tor versions (0.3.1.7 and 0.3.2.1-alpha
respectively) and above all the usual Firefox security updates by
including Firefox 52.4.0esr. Worth noting for both versions as well is a
fix for a crash bug that could kill all tabs if one closed a single tab.
Tor Browser 7.5a5 contains for the first time content sandboxing in
Firefox enabled on Windows and Linux. Please give it a test as we
want to have this feature on the stable channel as soon as we can.
Included in this alpha, too, is a patch that will hopefully help our
users who run into crashes on Windows by backporting Mozilla code for
blocking libraries that are known to interfere with Firefox processes.
Apart from the release related work we focused on remaining Sponsor4
items. In particular, we finally switched to our new, rbm-based build
system which we used for the first time for official builds when
preparing the packages for Tor Browser 7.5a5. We made progress as
well working on 64-bit builds for Windows and testing UBSan for
finding bugs that are the result of undefined behavior. Our
improvements to the Tor Launcher UI are starting to emerge, too, thanks
to the collaboration with the UX team.
The full list of tickets closed by the Tor Browser team in September is
accessible using the `TorBrowserTeam201709` keyword in our bug tracker.
In October we plan to finish our Tor Launcher UI improvements, get our
Security Slider update done and will hopefully have some Tor Browser
nightly builds for 64bit Windows available. We'll continue testing
further Tor Browser hardening techniques like UBSan, STACK, and
Intel's MPX and start experimenting with improving our bridge
distribution in Tor Launcher.
All tickets on our radar for this month can be seen with the
`TorBrowserTeam201710` keyword in our bug tracker.
