Goals

• Platform/2011-Q3-Goals
  • Please update status
• Platform/2011-Q4-Goals
  • Please consider "mobile first", "how will we use telemetry", and e10s

Notices / Schedule

• The 3.6.23 → 7.0.1 advertised update is happening this Thursday

Firefox Development

• Preliminary set of Firefox e10s bugs filed, many more to come (bug fxe10s)

GFX

• Graphics BugKill day this Friday, October 7.
  • We'll be spending our full day triaging our old bugs, trying to get down to a manageable number.
  • If you're interested in participating or observing, please email Joe now.
• Draft Q4 goals for the Graphics group are now available.
  • If it's on the goals list, we'll be focusing on it in earnest with a plan of finishing it this quarter.
  • If it's on the "Other important Q4 work" list, we'll probably be working on it, but it's either not big enough to be a goal or unlikely to be finished in Q4.
  • We include both goals and "Other important work" to ensure both: that you know what we're working on, and that we're always working on the most important thing.
  • Please let us know if this isn't the right set of goals!

Layout

• CSS 3D transforms enabled on trunk! (mattwoodrow) bug 505115
  • some improvements coming
• Image animation now controlled by refresh driver; should improve performance substantially on pages with lots of animated images, especially in background tabs (Scott Johnson) bug 666446
• Major ancient table-related bugs fixed (table margin collapsing, use of relatively positioned tables as containing blocks for absolutely positioned descendants) (ehsan) bug 10209

Video

• Fine-tuning fullscreen API so we can enable it on trunk, did security review (cpearce)
• Working on measuring and reducing the latency of media element playback, so patterns like "element.clone().play()" work well when you just want to play lots of sounds (doublec)

Mobile

Mobile Perf Program Wiki has landed. This has engineering and testing goals and status. https://wiki.mozilla.org/Mobile_Performance

Last week: We have a testing matrix people seem happy with. Check out the above wiki page to review. We are also covering iOS browsers on Apple HW. I will find a more permanent home for this info.

This week: We need to land on standardized methodology for testing and analysis. I am drafting this up and will shop around to eng and qa for approval in time for Aaron Train's QA testing day this Friday.
