Phoenix 2026.09.29.1

Changes

IMPORTANT: We've officially migrated our issue tracker to a new, unified one on Codeberg. Please note that issues will no longer be accepted on GitHub, GitLab or in any repo outside of the new unified Codeberg issue tracking repo).

• Disabled AI Speech Recognition by default.
• Enabled the ML-DSA post-quantum signature scheme by default.
• Enforced Safe Browsing in all contexts by default (so that checks are also applied to iframes, in addition to top-level channels).
• Other minor tweaks, fixes, and refinements.

Desktop-only

• LINUX: Disabled Geoclue by default (to reduce our reliance on OS-provided/external services, in favor of the browser's built-in network geolocation provider).
• non-OS X: Explicitly enabled the network geolocation provider by default, to ensure that it's properly enabled, instead of just relying on the fall-back/testing provider.
• Added DNSBunker and dnsforge.de to the list of built-in DNS over HTTPS providers.
• Disabled fetching GMP plug-ins from Chromium servers (if GMP is enabled) to prevent additional unnecessary connections to Mozilla.
• Disabled the Remote Settings-backed new tab renderer.
  • This also fixes an issue that caused favicons to not display properly on about:home for some users.
• Disabled reliance on OS location services/system permission for geolocation, so that the network geolocation provider can always fall-back/work properly as expected.
• Prevented the browser from automatically downloading tab group AI models (if the relevant functionality is enabled).
• Set Firefox Sync to use a generic default device name to avoid leaking the username and device hostname/model to Mozilla (as well as whether a user is using a fork).
• Disabled recent search widgets on about:home by default, but enabled the UI to allow users to enable them if desired.
• Enabled the ability to control media playback speed for media in Picture-in-Picture windows by default.
• The new Unified Trust Panel is now only disabled on ESR, due to the removal of Firefox's cookie banner blocker on release.
• Disabled newly-added Firefox Sync client info ping/telemetry.
• Disabled Mozilla VPN promotional messaging on about:home.

Specialized configs

• Disabled search actions.
• Disabled URL bar mentions.
