New Release: Tor Browser 11.0a10 (Windows/macOS/Linux)

by sysrqb | November 5, 2021

Tor Browser 11.0a10 is now available from the Tor Browser 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 Windows/macOS/Linux release instead.

This version updates Firefox to version 91.3.0esr on Windows, macOS, and Linux. This version includes important security updates to Firefox on Windows, macOS, and Linux.

Please report any issues and regressions you experience since upgrading from an earlier version based on Firefox 78esr.

Tor Browser Alpha does not support version 2 onion services. Tor Browser (Stable) will stop supporting version 2 onion services very soon. Please see the deprecation F.A.Q. entry regarding Tor version 0.4.6. Migrate your services and update your bookmarks to version 3 onion services as soon as possible.
