Action items

Feature Status Review

• Firefox 84 BETA
  • [At Risk] Initial support for Firefox on Apple Silicon - Extremely high crash rate on MacOS devices. Pursuing options to either remedy these crashes or postpone arm64 rollout to Fx85.
• Firefox 85 NIGHTLY
  • [At Risk] Full Rollout of the new Modernized Print UI - Preliminary QA status and an outstanding blocker is likely to block the experiment rollout in Fx84. This would cause the overall release (currently planned for Fx85) to be postponed to Fx86. Expect a decision on this soon.
  • Ion enhancements scope not yet finalized for Fx85. Consiering we are so close to Nightly I assume it'll just be whatever happens to land before the Nightly soft code freeze. No action to take here. @Tania - Do we have cocnerns about the lack of feature scope and what's been requested from QA for this Nightly cycle?
