Action items

Feature Status Review

  • Firefox 122 (Beta)
    • Enable the 1-click set to default option for MS store users remains CHALLENGED as this work may not be able to ship with Fx123. Team is working through the blockers.
    • WDBA porting into background tasks - Phase 2 marked as CHALLENGED before the year-end holidays as the team needed to uplift some work in Fx122 beta. Working to confirm the status of that uplift and next steps.
    • Android and iOS had planned to roll out Review Checker by default and start a Review Checker ads experiment in Fx122, but both have been postponed until Desktop runs another Review Checker UX experiment. No ETA for the mobile rollout or experiment, but no sooner than March.
  • Firefox 123 (Nightly)
    • No challenged or at risk features at this time!
    • CSSLoader OnStopRequest - OMT slipped to Fx124 as it will not be ready in time for soft code freeze.
