Action items

Feature Status Review

• Firefox 82 Beta
  • [challenged] Modernized print UI - Challenged due to performance regressions. Team is monitoring telemetry. Unclear what the go to green plan is here. Investigating.
  • [challenged] Move Search TopSites into Remote Settings - Work was recently deferred to Fx82 as we did not make it into Fx81 before RC week. Working to identify the go to green plan here.
  • [challenged] "Wizardless" Password Autocomplete Import Experiment - Challenged due to a number of known uplifts required. Will return to green when those land at the end of this week.
    • [jcristau] discussing with the team now to better understand the risks/benefits
• Firefox 83 Nightly
  • [challenged] Improve QB (V2) Search Discovery : Search Shortcuts - Challenged as this is a large body of work and the team is not sure if they will get this completed in time for the soft code freeze. Should have a better confidence after a planning meeting this week.
