A new alpha Tor Browser release is available for download in the 5.5a3 distribution directory and on the alpha download page.

This release features important security updates to Firefox.

Beginning with this alpha version Tor Browser is available in Japanese as well. In addition to that it contains usability improvements for our font fingerprinting defense, a better notification of Tor Browser changes after an update and regression fixes that were caused by our switch to ESR 38 back in August.
