[tor-qa] Tor Browser 10.0a5 is ready for testing

Sun Aug 16 20:39:57 UTC 2020

Hello!

We are happy to announce that the first alpha for desktop users based on
Firefox 78 ESR is ready for testing. Bundles can be found at:

https://people.torproject.org/~gk/builds/10.0a5-build2/

We announced nightly builds based on ESR 78 a while ago[1] and used the
time since then to adjust our toolchains, finish our proxy audit, and
fix a lot of issues that came down on us due to the switch to this new
major Firefox version on the ESR channel.

Tor Browser 10.0a5 ships with Firefox 78.1.0esr but there are a lot more
changes that we included compared to the previous alpha version. As it
is the first alpha based on the new major ESR version we expect more
bugs than usual. Please report them, either here or on Gitlab[2], or
essentially with any other means that would reach us. We are in
particular interested in potential proxy bypasses which our proxy audit
missed.
