Blocker Report

• Firefox 3.6.4
  • Nothing blocking, but watching this query to make sure nothing is missed

GFX Update

• Harfbuzz landed! bug 449292
  • It's turned off by default. To turn it on:
    • Set gfx.font_rendering.harfbuzz.level to 1; harfbuzz will be used for "simple" scripts (Latin, Cyrillic, CJK) that do not require specific complex shaping.
    • You can set it to 2; Harfbuzz will then be used for all scripts (even though the results will currently be broken).

Hardware Acceleration Update

• OpenGL and OpenGL ES acceleration won't make it for Q2.
  • To talk more about this, please participate in the dev.planning thread.

Layout Update

• WebM landed and shipped in 1.9.3 alpha.
  • Need to work on performance, especially non-accelerated scaling; will probably use more of the Chrome code [doublec]
  • Working on 'buffered' TimeRanges; implemented for Ogg and Wave, working on WebM [cpearce, kinetik]
• Harfbuzz landed, currently off by default [jkew, jdaggett]
• Retained layers basically ready for review, just wrangling a few test failures [roc]
  • Optimized scrolling of background-attachment:fixed in hard cases (faster than Safari)
• Reorganization of frame coordinate systems for zooming just about ready for review [tnikkel]

Content Update

• Necko e10s changes getting close to landing in mozilla-central (jduell)

Tree Management

• New mozilla-1.9.3 / mozilla-2.0.0 branch work blocked on figuring out which version # to use

Roundtable

• Are we happy not including the XPCOM changes (and any related Gecko version bump) in beta 1? (Mossop)
• Some feedback from Linuxtag (Pike):
  • Getting rid of restarts, updates not in startup is a perfect match with people
  • Hard to tell how much of perf comparison with chrome is apples-to-apples, both in platform integration and extension ecosystem/capabilities. Recent blog and forum posts helped.
  • Having plans for shoveling tasks to other processes and GPU is good, should deliver something noticeable in Fx4
  • Adblock+ is something like a Firebug, in that people evaluate "the browser that run adblock+". Recent perf blog by Wladimir helped a bunch, but people don't mind that much who's at fault. Can we expose better APIs for him?
