Notices / Schedule

Please focus on bugs tracked for FF15 and FF16

• FF14.0.1 was unthrottled last Thursday, based upon early post-release feedback
• FF14.0.1 post-mortem held this morning - discussion focused on plugins and update uptake
• FF15 beta 3 (of 6) going to build today, will be released before the end of the week

Firefox OS

• Milestone 5 - focusing on wrapping up the feature work that's left, polishing UI, bug fixing and performance optimizations
• Gaia app updates are at https://etherpad.mozilla.org/gaia-meeting-notes
• Identity and WebAPI updates are below.

• Technical Release Plan partially signed off after driver meeting last week, more details soon
  • Focus was on short-term decisions (branching, updates, testing, etc.)
  • ESR17 will be the Gecko basis for B2G v1. See email to enterprise list and dev.platform soon.
• Blockers for internal dogfooding and external testing have been identified and are being prioritized
• Hardware dogfooding now has all interested parties involved (including IT and engagement)

Firefox Development

• Social: bug 764869, bug 764872, bug 773351, bug 770695: big pieces of the work that makes Social actually semi-usable have landed. That means that you can test social features using "MoTown" in Nightly builds, by setting social.enabled = true.
• bug 769960 landed this weekend, big cleanup of safe browsing front-end code by dolske, paves the way for additional cleanup (bug 775851) and better code re-use from mobile and other apps

• (catlee) What's the status of the stub installer work? When are we aiming to land this? What changes are required for RelEng?

Firefox Developer Tools

• Source map library landed. bug 669999
• New HTML panel underway
• Web Console in Iframe bug 688981

Add-on SDK

Performance

• This week's Snappy summary

• BenWa blogged about Javascript Profiling with The Gecko Profiler and JS Anti-pattern
• JS support in the SPS profiler has lead to the first two Snappy add-on bugs. (bug 777266, bug 777397). Here's what to do if you discover an add-on with potential responsiveness issues.

• Nick Hurley blogged about his research into cache usage results
• According to telemetry, 10-20% of start-ups feature cache nuking. Brian Bondy used telemetry to investigate causes for cache purges in bug 774146.
• And Brian landed a fix to lower IO priority of nuking our cache (bug 773518).

• Tim Taubert made our new tab animation more pleasant (bug 716108).
• Tim also landed a fix to halve jank caused by thumbnail capture (bug 774811), which should result in a better tab-switching experience.

• Jon Coppeard enabled incremental GC sweeping (bug 729760), which should result in slightly smaller GC pauses.

GFX

• Azure content (currently enabled for Direct2D, i.e., hardware accelerated Windows Vista and 7) is being turned off for Firefox 15 (currently in beta) due to regressions.
  • It's staying on in 16, though.
  • The new 2D API is still our future, it's just not ready for prime time yet.

JS

• ES6 - Maps and Sets are iterable (bug 725909) re-landed for Fx17. Read more at Harmony iterators. Jason Orendorff.

Layout

• off-main-thread animations bounced for breaking Fennec Native but relanded today
• window.sizeToContent() no longer adds an extra pixel (bug 230959)
• Scott Johnson posted blog post on font inflation on mobile

Stability Report

Socorro

Desktop

Flash

• Stability team is continuing to closely examine the effects of the .268 Flash release last week
  • We need a few more days worth of data to see the true effect
  • Overall, it looks like it improved the situation somewhat but there's still a lot to be done.
  • bsmedberg has a series of reports that are run summarizing the flash situation - https://crash-analysis.mozilla.com/bsmedberg/flash-summary.html
  • KaiRo generated another view here: https://crash-analysis.mozilla.com/rkaiser/2012-07-30/2012-07-30.firefox.flash.11-3-300-268.html
  • Please let marcia know about 100% reproducible flash crashes, especially ones that Adobe cannot reproduce on their end.
