Hello everyone!

We are pleased to announce that we finally have a release candidate for
Tor Browser 8.0a9 available for wider testing. After fixing a bunch of
release relevant bugs during manual testing here are the bundles that
could become Tor Browser 8.0a9:


Please give them a try if you can!

Tor Browser 8.0a9 is the first alpha based in Firefox 60 ESR. We rebased
all of our patches and updated our toolchains to pick up new
requirements like Rust support.

This alpha contains a bunch of new features which we hope to stabilize
until Tor Browser 8 gets stable. Most notably we

1) improved our circuit display and moved it from the Torbutton menu to
the identity box in the URL bar domain stressing its strong ties to the
URL currently visited.

2) added support for .onion security indicators giving you a little
onion icon instead/in addition to the padlock icon in the identity box.

3) added four new locales, da, he, sv-SE, and zh-TW to give users
spekaing those languages an improved Tor Browser experience. The plan is
to add even more locales once we are confident we can handle the
additional load and disk space requirements.

4) replaced our old Torbutton icon with a shiny new one. That's the
first step in redesigning our icons and making them compatible with
Firefox's Photon UI. There is more to come in the next alphas.

5) are able to provide full content sandboxing support for 64bit Windows
bundles thanks to the work done by Tom Ritter.

Additionally, we updated a number of components we ship: Tor to, Torbutton to 2.0.1, TorLauncher to,
HTTPS-Everywhere to 2018.06.21, and NoScript to Expect more
bugs than usual in this alpha.

Which brings me to the known issues section. The most important ones are
listed below:

1) We are still investigating why our generation of incremental update
files are failing. We might not have fixed that in time for this release
which means only the full update files might be available.[1]

2) Meek is currently broken. We need to update the browser part for make
it compatible with ESR60.[2]

3) On Windows localized builds on first start the about:tor page is not
shown, rather a weird XML error is visible.[3]

4) Maybe related to 3) NoScript does not seem to work properly on
Windows builds right now.[4]

5) We are not done yet with reviewing the network code changes between
ESR52 and ESR60. While I don't expect that proxy bypass bugs got
introduced between those ESR series, I can't rule it out yet.[5]

6) We disable Stylo on macOS due to reproducibility issues we need to
investigate and fix.[6]

If any of you will find more issues (and I hope you do) please report
them at https://bugs.torproject.org. We track all Tor Browser 8 related
issues with the ff60-esr keyword.
