New Release: Tor Browser 11.0.3

Tor Browser 11.0.3 is now available from the Tor Browser download page and also from our distribution directory

This release updates Firefox to 91.4.1esr and picks up a number of bug fixes. In particular, this release should fix various extension related and crash issues Windows users were experiencing. Additionally, Linux users especially on Ubuntu and Fedora systems were reporting fonts not properly rendering, which should be solved by this release.

We used the opportunity to upgrade various components to their respective latest versions as well: Tor to 0.4.6.9, OpenSSL to 1.1.1m, and snowflake for enhanced censorship resistance.
