New Alpha Release: Tor Browser 11.5a2 (Windows, macOS, Linux)

Tor Browser 11.5a2 is now available from the Tor Browser download page and also from our distribution directory.

This version includes important security updates to Firefox.

Tor Browser 11.5a2 updates Firefox to 91.5.0esr and includes bugfixes and stability improvements. Additionally, the browser landing page gets the usual Tor Browser look and feel back, removing the parts of our year end donation campaign.

We use the opportunity as well to update various other components of Tor Browser: Tor to 0.4.7.3-alpha, OpenSSL to 1.1.1m, and NoScript to 11.2.14. We switch to the latest Go version (1.17.5), too, for building our Go-related projects.

As usual, please report any issues you find in this alpha version, so we can fix them for the next upcoming major stable release (11.5).
