shutdownhang | NtWaitForKeyedEvent | RtlSleepConditionVariableSRW | mozilla::TimeStamp::Now | GetTickCount64 | SleepConditionVariableSRW | mozilla::detail::ConditionVariableImpl::wait | mozilla::CondVar::Wait | nsEventQueue::GetEvent | nsThread::nsChai... needs a bug. Comments mention freezing and crashing. Might be an antivirus issue and need to look at the correlations.

User Advocacy


  • We have slack (!) channel to discuss about 57 triage:
  • e10s-multi to 100% for 55? only users with webextensions based add-ons get e10s-multi. In 57 only webextensions will load - so add-ons won't be a blocker for users getting e10s-multi by 57.
  • war room for 56? did that work for 55?
    • It was ... not useful ? :) I used the slack channel to give updates, I think some people appreciated the updates, almost nobody showed up in the vidyo as I prepared everything Paris morning time
      • which slack channel?
  • Nightly renamed to Firefox Nightly
