  • M9 bug 1266575 - [E10s] click event is not dispatched to <select> when clicking on opened popup
    • Fixed and landed. Will request uplift today (all the way to 47?)
  • bug 1166351 - XBL parent bindings not properly attached - tabs suddenly do not switch or close properly
    • Finally figured this out. Landed on inbound last night. Check out the last few comments in that bug if you want the gory details.
    • From what I can tell, this is probably a bug that got introduced in 2014. Dunno why it started rearing its head more aggressively this year.
  • bug 1261842 - Make initial browser remote sooner if we're defaulting to using remote tabs
    • My refactor is done (locally), and now I'm doing test clean-up, because making the initial browser remote seems to change some assumptions in various components.
  • My Outreachy intern Rutuja Serve starts on Monday!
    • She's Rutuja in IRC.
    • She's working on bug 1255843 - Develop a tool to measure resource usage of each subprocess
      • Got support from njn and erahm on this. Starting our work based on some stuff :past did for lightweight measuring of per tab memory.
  • The usual slew of reviews and feedbacks and needinfos
    • Did a bunch of review clean-out this week. If I haven't gotten to you yet, I will today.

  • bug 1259480 - (crash - FatalError crash in PContentChild::Read from PContentChild::SendReadPrefsArray) - looked into the pref parser to find something fishy that can cause the message corruption. Did not find anything that could cause the problem.
