Performance (Thu)

Aurora / Dev Edition




request expanding multi to webextensions later in 54 (after throttle to 100% and initial multi + no add-ons data comes in). Benefit: Multi + webextension is a 57 requirement and earlier release de-risks 57 + Multi to broader audience. Issue: we have seen 1 more content crash per 25,000 hours than Multi with no add-ons. Stability wise believe that is minor change the crash is 25% from EnqueuePromiseReactionJob. Fixes that landed in Beta 54 don't seem to have impacted, more are riding with 55. asking for data on that in nightly

to do: email release drivers and gerry chang (54 release owner)

  • [marcia] Where do I find the plan of what we will support on Android O? I asked in #mobile on slack - it sounds as if we have to support SDK - "Sure file a bug, we should change implementation if we upgrade fennec to use sdk 25 some day. "
    • marcia will reach out to Joe Cheng regarding this
  • Meta Bug - Sebastian is asking for triage in many of them so I guess they are not sure yet.
