Necko (dougt/jduell)

• Looking into the HTTPS/TLS feature set of our new search partners: short answer is they're behind Google on some issues.

Performance (vladan)

1. What has your team done since last week that might impact others?

• Firefox responsiveness metric:
  • We landed a Telemetry probe that measures delay in ms between the target and the actual handling time of the frame at refresh driver
    • http://mzl.la/1zRFtOP
• Looked at BHR data to determine how common are plugin hangs:
  • Preliminary data from one day on Nightly (not reliable!): https://etherpad.mozilla.org/tKgLhkkTVe
  • More reliable data from Aurora: http://robertovitillo.com/2014/11/25/clustering-firefox-hangs/
  • These numbers help set expectations for benefits of aklotz's async plugin init patch & Shumway work

2. What will your team do this week that might impact others?

• Portland: Roberto will hold a tutorial on analyzing Telemetry data using Spark, a much faster way to do custom analyses of large amounts of Telemetry data
