Tor Browser 16.0a12 is now available from the Tor Browser download page and also from our distribution directory.This version includes important security updates to Firefox.⚠️ Reminder: The Tor Browser Alpha release-channel is for testing only. As such, Tor Browser Alpha is not intended for general use because it is more likely to include bugs affecting usability, security, and privacy.If you are an at-risk user, require strong anonymity, or just want a reliably-working browser, please stick with the stable release channel.Windows Package Signature IssueThe DigiCert EV code-signing certificate we use to sign Windows installation packages is expired since September 1st and we are currently in the process to renew it. Unfortunately, this process is delayed and not yet complete.Therefore, trying to install Tor Browser 16.0a12 or 16.0a11 from scratch will cause a "bad signature" warning on Windows.Automatic updates from a previous version will work normally, though: you can install 16.0a10 and let it update to the lastest version.Send us your feedbackIf you find a bug or have a suggestion for how we could improve this release, please let us know.Full changelogThe full changelog since Tor Browser 16.0a11 is:All PlatformsUpdated Tor to 0.4.9.12Updated NoScript to 13.6.33.90101984Bug tor-browser#45304: Rebase Tor Browser alpha onto 153.3.0esrBug tor-browser#45336: Pass --disable-proxy-direct-failover in our mozconfigsBug tor-browser#45299: Backport Security Fixes from Firefox 156Bug tor-browser-build#41846: Sign alpha releases using new gpg subkeyBug tor-browser-build#41875: Update relprep.py for the new versions.ini URLWindows + macOS + LinuxUpdated Firefox to 153.3.0esrBug tor-browser#42065: Security exception warning and button for Onion Services with self-signed certificatesBug tor-browser#45133: Disable browser.toolbars.share-button.enabledBug tor-browser#45177: Remove websiteSpoofEnglishControlBug tor-browser#45249: Remove the duplicate "Verified by" from the old site identity panelBug tor-browser#45255: Add YEC 2026 Strings (Desktop)Bug tor-browser#45262: Disable reset PBM burn button and related UI migrationBug tor-browser#45277: Change setting icon for About Tor BrowserBug tor-browser#45278: Explicitly disable WebXRLinuxBug tor-browser#44887: Drop Linux 32-bit deprecation noticeAndroidUpdated GeckoView to 153.3.0esrBug tor-browser#44548: Remove "Passwords" UI from AndroidBug tor-browser#44936: Search widget icon is too small on android alphaBug tor-browser#45100: Regression in #43229 "Buttons that open links can be accessed before torbrowser is bootstrapped, leaving the app in a bad state"Bug tor-browser#45172: Move our "Connect to Tor before opening links" code from the deprecated openToBrowserAndLoad to the recommended loadUrlOrSearchBug tor-browser#45217: Implement YEC 2026 Takeover for Android StableBug tor-browser#45225: Remove "Share" and "Translate" options from "Settings" -> "Customize" -> "Toolbar shortcut"Bug tor-browser#45250: Remove "Privacy report" in tabs settings in AndroidBug tor-browser#45251: Turn off and hide the remote improvements UIBug tor-browser#45252: Remove the change wallpaper menu itemBug tor-browser#45256: Add YEC 2026 Strings (Android)Bug tor-browser#45261: Add linter check: only MAIN+LAUNCHER components may be exported="true"Bug tor-browser#45269: Completely disable search suggestion featureBug tor-browser#45275: Drop clearOnShutdown on Android-specific profileBug tor-browser#45280: about:config broken on AndroidBug tor-browser#45281: Fix or remove broken "Use screen lock to hide Tor Browser tabs" featureBuild SystemAll PlatformsBug tor-browser-build#41867: Update tails-dev email address in release prep templatesBug tor-browser-build#41871: Update downloads repository references in relprep templatesWindowsBug tor-browser-build#41877: make list_toolchain_updates is not checking windows-app-sdkBug tor-browser-build#41878: Update the Windows app SDK and add some additional DLLsAndroidBug tor-browser-build#41876: Add missing firefox_platform_version.txt file in android artifacts directories applications releases
