QA

• Trello has been having issues since yesterday, our status boards may temporarily be unavailable - see https://status.atlassian.com/

Nightly

• MR2 - kick-offs have been held, TP & TCs creation started, also execution where Nightly testing was requested, with the exception of https://mozilla-hub.atlassian.net/browse/QA-1135 which should be ready for testing starting tomorrow
• There is potential for a notable startup perf regression due to additional themes. Investigation by engineering in progress.

Beta

• Pre-Release reports are in progress
• Win 11 - final round of testing will start soon, ESR 91 to be covered as well
• Win 10 21H2 update - 2nd round of testing completed today, no related issues found, Nightly 94 and ESR 78 were covered as well

Feature Status Review

• Firefox 93 - On Track
  • Smartblock 3.0 is ready ahead of schedule and will rollout in Fx93 without any uplifts
  • Another uplift inbound for AVIF; https://bugzilla.mozilla.org/show_bug.cgi?id=1731404. Feature still targeting Fx93.
• Firefox 94 - Challenged
  • Challenged status mostly driven by MR2 scope
    • Waiting on onboarding requirements for Monochromatic themes. Seems highly likely we'll have uplifts during the beta cycle. There's also some concern around startup perf. Not a blocker but something to be aware of.
    • Another MR2 objective 'New users don’t get interrupted when closing Firefox' was expected to be dev complete already. Marked as challenged. New devcomplete date is 9/22.

SUMO Report

• Findbar close button escapes findbar-close-container on MacOS: https://bugzilla.mozilla.org/show_bug.cgi?id=1728368
  • fixed with a dot release
