Firefox/Meeting/02-Feb-2016

Actions from last meeting

• None

General Topics / Roundtable

(tips/tricks/FYI, productivity improvements, industry news)

• [mconley] Unsafe CPOWs are outlawed in browser code
  • If you start seeing "unsafe CPOW usage forbidden" in the Browser Console for various things, please mark them blocking bug 1233497 (bug 1233497 )
  • Also see: https://groups.google.com/forum/#!topic/mozilla.dev.platform/Nstdr9vsSWI
  • Add-ons should be mostly immune to this restriction, with some caveats - JSMs get their own compartments, so passing CPOWs into browser JSMs and having them use them is no bueno.
  • Talk to me (or send folks to me or #e10s) if there are issues here.
• BMO Component Owners
  • https://docs.google.com/spreadsheets/d/10i30CFUPJM7snz0xX3czFJeBh2tNwjwjtI409DQw3x0/
• No need to rev UUID for XPIDL changes anymore
• Statuser BHR (Browser Hang Report) realtime reporting
  • https://github.com/chutten/statuser
• [bgrins] two browser toolbox notes:
  • debugger statement will get hit even if debugger panel hasn't been opened (if Browser Toolbox is already opened)
  • reminder - devtools.debugger.prompt-connection pref can make the prompt before opening go away
    • Bug 1013379 is opened to make this automatic for local connections
  • autoclose panel debugging stuff
    • bug 950936
      • fixed for 47 - should be a button for this in your browser toolbox today
• (bsmedberg) Install/Update team commitments and priorities: https://trello.com/b/Ldf65oOF
• (bsmedberg) Restructuring of the Performance Team - https://docs.google.com/a/mozilla.com/drawings/d/1ZjXYNDXVTixn4LKJicwUv_F8EmjLNea74HwBLopJ4H8/edit?usp=sharing

Project Updates

Add-ons

• [mconley]: http://arewewebextensionsyet.com/
• [mconley]: A Chrome extension porting story: https://github.com/notwaldorf/github-canned-responses/pull/2
  • Now available in AMO: https://addons.mozilla.org/en-US/firefox/addon/github-canned-responses/

E10s

• [mconley] Telemetry experiment is underway!
  • e10s is enabled for a subset of the beta population (with and without add-ons)
  • I believe the primary goal of this first experiment is to get a sense of which add-ons hurt us e10s the most
• A second experiment will be shipped that measures performance and stability for a subset of the beta population that has no add-ons whatsoever
  • I believe this will be used to help inform / bolster a go-nogo for 46 for users without add-ons.
• [mconley] Please be vigilant about filing (or bumping) any potential e10s blocker bugs, because (modulo perf or stability regressions from the experiment) we seem to be approaching the end of the runway for v1. \o/
• [felipe] e10s tests: https://docs.google.com/spreadsheets/d/10UeyRoiWV2HjkWwAU51HXyXAV7YLi4BjDm55mr5Xv6c/edit?pref=2&pli=1#gid=0
  • areas that need focus
