Hi,
we are about to start a hardened Tor Browser series and the first nightly for it is ready to get tested (on 64bit Linux systems):
https://people.torproject.org/~gk/testbuilds/tor-browser-linux64-tbb-nightly... https://people.torproject.org/~gk/testbuilds/tor-browser-linux64-tbb-nightly...
Its major features are:
1) expensive hardening for tor (ASan, UBSan...) 2) ASan for the browser 3) the locales we ship/support are included in one bundle allowing to choose the locale for Tor Browser on start-up
We plan to have something like 3) for the regular alpha and stable series in the (near) future as well. Thus, testing it and providing feedback is extra welcome.
Georg
P.S.: One bug I already found is related to the fact that the set of locales we include in the nightlies is not the same as Tor Launcher is assuming. Thus, 3) only works properly while choosing one of en-US, ar, ru, ja and zh-CN (and having the OS locale be one of them, too). This is bug 17399.
