Action items

Feature Status Review

• Firefox 95 Beta
  • More From Mozilla about:preferences experiment Phase 1 & TCP Opt-In (Continuous Onboarding) are both considered challenged pending the approval of a few uplifts
    • Working to get the bug numbers here @relman - Can you tell me if these have been approved?
  • All other features remain On Track
• Firefox 96 Nightly
  • Waiting on updates around; Support microsoft-edge default work & Support pdf default work. Still consider these likely to slip considering how far along we are in the Nightly cycle
  • Addon-Gated WebMIDI moved to Challenged status this week as the overall timeline is very tight for making Fx96. Mitigation strategy seems to be simply to push to Fx97 if the work isn't completed in time.

• SIDE NOTE; working to get the UJET project using the weekly status and last comment functions in Jira. Hopefully we will be rid of the blank sections within the Release tracking mana pages very soon!
