[75.0]

• no visible crash spike from intel gemini lake cpus this time in 75.0/rc3
  • Same for ESR?
    • not enough data there yet at this point
    • No signs of bug 1524257 in 75.0 or 68.7.0esr releases (8000+ in 68.6.1esr, 400+ in 74.0.1)

Mobile Stability

Fennec

• Crash rate is calculated based on usage hours (the time Firefox is actively used).
• Usage hours will be significantly lower on Fennec than on desktop Firefox, so we can't compare mobile rates to desktop rates.

QA

Nightly

• PI Request deadline: Friday, April 10th, mostly carryover features from past releases
• Private relay: Awaiting documentation, PI tickets to be updated, QA is following up

Beta

• on track, more updates expected next week
• Feature currently in backlog, QA not sure if it still requires testing in beta
  • https://trello.com/c/ApO21lp6/908-enable-windows-mac-linux-process-sandboxing-for-the-socket-process-which-is-used-for-webrtc-only-at-this-time (overholt's understanding is that this is being held in beta but Nils would know for sure)

Feature Status Review

• windows default browser agent (shipped in 75) sends telemetry to the wrong place
  • investigated and found out QA had an offline discussion however it looked okay as per the feedback received from Eng, no bug was filed by QA
• ETP: Cookie Restrictions: List 2 remains challenged waiting on Google experiment data
• Private Relay features remain challenged but not expected to ship with Fx76
• RDM Fission re-work slipped to Fx77

User Advocacy / SUMO Report

• [roland] - I'm at another meeting. I don't see any questions that indicate issues in 75 from UTC 0001 until 830a.m. pacific but perhaps Philipp has seen something overnight from Europe?
