Action items

Feature Status Review

  • Firefox 122 Beta
    • Enable the 1-click set to default option for MS store users marked as CHALLENGED as this work may not be able to ship with Fx123. Team is working through the blockers.
    • Implement RSA Blind Signatures (behind pref) slipped to Fx124 as the team is still working through reviews and has not yet decided on the final API that will be exposed
    • 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
    • Support Curve25519 in WebCrypto slipped to Fx125 as the code within Hacl did not meet our standard requirements as it generated some sub-dependencies that will be hard to maintain. Due to some competing priorities we shift the delivery of this work to Fx125.
    • Release tracking page is now live in confluence
    • 24 Desktop & 15 Android/iOS Jira issues already targeting Fx123
