Tor Browser 12.0a4 is now available from the Tor Browser download page and also from our distribution directory. Tor Browser 12.0a4 updates Firefox on Android, Windows, macOS, and Linux to 102.4.0esr. This version includes important security updates to Firefox and GeckoView. There were no Android-specific security updates to backport from the Firefox 106 release. What's new? Tor Browser 12.0a4 includes a number of changes that require testing and feedback: Multi-locale bundles (Desktop) This is the first multi-locale release of Tor Browser Alpha for desktop. All supported languages are now included in a single bundle, and can be changed without requiring additional downloads via the Language menu in General settings. What to test: Tor Browser Alpha should default to your system language on first launch if it matches a language we support. Alpha testers are also encouraged to test changing language within about:preferences#general, and to report any new bugs with localization in general. tor-launcher migration (Desktop) Parts of the code that power tor-launcher – which starts tor within Tor Browser – have been refactored. Although this work doesn't include any changes to the user experience, those who run non-standard Tor Browser setups are encouraged to test 12.0a4 on their systems. What to test: Alpha testers who run non-standard Tor Browser setups (including, but not limited to, those who use system tor in conjunction with Tor Browser) should test starting and connecting to Tor, and report any unexpected error messages they encounter. All of the previously supported environment variables should still behave the same way as in the stable series. Onion Auth fixes (Desktop) 12.0a4 includes two fixes to Onion Service client authorization: 1. A fix to the auth window itself, which was broken in Alpha due to a regression caused by the esr102 transition: tor-browser#41344 2. Another fix to a longstanding issue with Onion Auth failing on subdomains, which has also been backported to 11.5.5: tor-browser#40465 What to test: Accessing client authorized Onion Services on both top-level and subdomains. Always prioritize .onion sites (Android) Android users can now enable automatic Onion-Location redirects by switching "Prioritize .onion sites" within Privacy and Security settings. What to test: Enable "Prioritize .onion sites" within settings, visit a website that supports Onion-Location, and verify that you were redirected to the website's .onion address. Unified Español locale (Desktop and Android) Previous versions of Tor Browser Alpha were available in both "es" and "es-AR" (Español Argentina) locales. In Tor Browser 12.0a4 these have been unified into a single Spanish locale instead. What to test: Alpha testers who use the "es-AR" locale should be automatically switched to "es-ES" after updating.
