Tor Browser 12.5a2 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/12.5a2/).
This release updates Firefox on Android, Windows, macOS, and Linux to 102.7.0esr. 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 109 release.
We use this opportunity to update various other components of Tor Browser as well:
- tor 0.4.7.13
- NoScript 11.4.14
- go 1.19.5
