Phoenix 2026.01.21.1

NOTE FOR DESKTOP USERS: To allow for easier maintenance and updates, Phoenix's uBlock Origin assets have been moved to a separate, dedicated assets repository. While your uBlock Origin configuration should continue to work as expected, to avoid any potential issues/disruptions in the future, after updating to this Phoenix release, please complete the following steps to ensure your configuration is properly migrated:

• Towards the bottom of the Settings tab of uBlock Origin's dashboard, select Back-up to file..., and save a back-up of your uBlock Origin data.
• At the very bottom of the page, select Reset to default settings.... uBlock Origin's dashboard should close, and you should see uBlock Origin's icon turn yellow.
• Once uBlock Origin's icon returns to red, navigate back to the Settings tab of uBlock Origin's dashboard, and select Restore from file... (towards the bottom). Choose the back-up you created from the first step.

Additionally, regardless of whether you complete this migration or not at this time (you should), please also ensure that the Phoenix filters lists are still enabled under the Built-in section from within the Filter lists tab of uBlock Origin's dashboard. If you see duplicates of the Phoenix filter lists at the bottom of the Filter lists tab, please remove them.

Apologies for any inconvenience here, and appreciate your time and patience.

Changes

• Disabled RTP Control Protocol (RTCP) reception by default.
• Enabled Local Network Restrictions for top-level documents and for requests targetting the local device from the local network.
• Enabled multi-threaded media decoding and encoding by default.
• Implemented a proxy for Google Safe Browsing's remote download protection functionality.
  • The feature is still disabled by default (controlled with the browser.safebrowsing.downloads.remote.enabled preference), as it results in sending metadata of downloaded files to Google - but this improves the privacy for users who desire extra protection (at the cost of privacy) and wish to enable it.
• Updated the URL query parameter stripping list.
• Disabled and deregistered the new Glean add-on ping scheduler.

Android-only

• Enabled hardware/platform media decoding and encoding (1, 2) by default to improve performance and to fix media playback issues when isolated content processes are enabled.
