Tor Browser 12.5a3 is now available from the [Tor Browser download page](https://www.torproject.org/download/alpha/) and also from our [distribution directory](https://www.torproject.org/dist/torbrowser/12.5a3/).

This release updates Firefox on Android, Windows, macOS, and Linux to 102.8.0esr. It includes important [security updates](https://www.mozilla.org/en-US/security/advisories/mfsa2023-02/) to Firefox and GeckoView. There were no Android-specific security updates to backport from the Firefox 110 release.

We use this opportunity to update various other components of Tor Browser as well:

- NoScript 11.4.16
- OpenSSL 1.1.1t
- go 1.19.6
