New Release: Tor Browser 10.5a6

Tor Browser 10.5a6 is now available from the Tor Browser Alpha download page and also from our distribution directory.

Note: This is an alpha release, an experimental version for users who want to help us test new features. For everyone else, we recommend downloading the latest stable release instead.

This release updates Firefox to 78.6.0esr for desktop and Firefox for Android to 84.1.0. Additionally, we update Tor to 0.4.5.2-alpha for desktop users (Android users got that already with 10.5a5) and OpenSSL to 1.1.1i for everyone. This release includes important security updates both for desktop and Android users.

This version brings back a functioning meek bridge, and also allows users to automatically get bridges within Tor Browser again.

Note: Tor Browser 10.5 does not support CentOS 6.
