• issue with updates sometimes not getting applied has been resolved - https://bugzilla.mozilla.org/show_bug.cgi?id=1736373
  • random macOS crash signatures gone
  • likely caused by Firefox and breakpad builds out of sync, follow-up discussions in bug
  • Sebastian to check Nightly user retention / stuck on old builds

Mobile

Action items

Feature Status Review

• Firefox 94 Beta
  • New users don’t get interrupted when closing Firefox (https://trello.com/c/wqcfBNtz) has returned to 'On Track' this week with a green QA test report
  • 🎣 Fission Staged Rollout (0–100%) (https://trello.com/c/IdvWxYAt) was moved to 'Challenged' this week due to an identified blocker bug (https://bugzilla.mozilla.org/show_bug.cgi?id=1725572). Although a fix was landed and uplifted there is another unrelated concern within their crash rate telemetry that the team is watching closely. High confidence that Fission will roll out fully with Fx94 Release as planned (https://mana.mozilla.org/wiki/display/Firefox/Fission).
• Firefox 95 Nightly (https://mana.mozilla.org/wiki/pages/viewpage.action?pageId=150542965)
  • New Tab Custom Themes Selection (https://mozilla-hub.atlassian.net/browse/FIDE-617) is 'At Risk' as the UX designs still had not yet been finalized. Unclear if this is still targeting Fx95. Will likely require beta uplifts if Product decides to move forward.
