[tor-qa] Tor Browser 5.5a4 is ready for testing

[Georg Koppen]

Hi,

Tor Browser 5.5a4 is ready for testing. Binaries can be found on

https://people.torproject.org/~gk/builds/5.5a4-build2/

It features an updated Firefox (38.4.0esr) and Tor 0.2.7.4-rc + a number
of other improvements. Most notably, we included Yan Zhu's fix for not
leaking the Referer header when leaving a .onion domain and finally
sorted out the HTTPS-Everywhere build problems allowing us to ship its
latest version in our bundles again. We fixed usability issues coming
with our font fingerprinting patches and included a new defense against
figerprinting users via available MIME types and plugins. Finally,
besides additional minor bug fixes and clean-ups, we included an updated
NoScript version.
