Action items

Feature Status Review

  • [Challenged] DNS over HTTPS - Incident with [DoH Partner] increase in traffic breakage caused by rollout in Fx77. Fixed by 77.0.1 patch but [DoH partner] likely to be removed as a default provider moving forward over concerns of scaling costs.
  • [Challenged] ETP: Cookie Restrictions: List 2 - No changes here from previous reporting. Waiting on revenue impact data from Google. Expected in the next week or so.
  • Firefox Extension preference storage and sync work has been moved from Fx78 to Fx79. The team was planning to uplift changes to 78 beta that were not ready in time for Nightly. Decision was made to just slip the feature.
