Action items

Feature Status Review

• Firefox 92 - On Track
  • Last blocker around Supporting XFA PDF.js has been resolved. Moved from 'challenged' to 'on track'.
  • All other features considered on track. Mostly ready to just ride the trains as-is
• Firefox 93 - On Track
  • 'New users don’t get interrupted when closing Firefox' slipped to Fx94 due to a significant amount of outstanding work still needing to land
  • Still waiting on several features to become code complete. Likely going to come in toward the end of the cycle; see below.
    • Allow Firefox to restart to apply updates when no windows are open
    • Improve Mac install experience
    • MR2 The download panel UI is consistent with rest of Firefox UI
    • run-from-.dmg behavior changes
• Firefox 94
  • I'mmersive monochromatic themes can be enabled' this work MUST land in Fx94 based on Firefox Leadership priorities for shipping by year end. Engineering scope has the timeline at risk for delivery in Fx94 based on the amount of work required. Likely will be requesting uplifts during the Beta cycle.
