[tor-qa] Tor Browser 5.5 is ready for testing

[Georg Koppen]

Hi,

We are excited to announce Tor Browser 5.5 being ready for testing.
Bundles can be found on:

https://people.torproject.org/~gk/builds/5.5-build1/

This release contains an update to various bundle components: Firefox to
ESR 38.6.0esr, libevent to 2.0.22-stable and NoScript to 2.9.0.2.

Morevover, there are a bunch of new features worth mentioning. Above
all, we provide a defense against font enumeration attacks which we
developed over the last weeks and months. While there is still room for
improvement it closes an important gap in our fingerprinting defenses.

We ship Japanese bundles, start showing local change notes after an
update, isolate Shared Workers to the first-party domain, improved our
keyboard fingerprinting defense and added the onion service URL for the
DuckDuckGo search engine to name a few of the further features and bug
fixes.

Happy testing!
