GFX

• We think that OpenGL ES accelerated layer composition on Nightly builds for Android is ready to be tested by technical users.
  • There are still some known minor rendering glitches when pinch-zooming or panning; single frames are drawn at the wrong scale.
  • To turn it on, set layers.acceleration.disabled to false and layers.acceleration.force-enabled to true in about:config, and restart your browser.

Layout

• More 3D transforms stuff landed, some more to come before we can try turning it on by default (mattwoodrow)
  • Discovered an interesting regression on Facebook where they feed -webkit properties to any browser that Modernizr says supports 3D transforms :-(
• Jonathan Kew persuaded some authors of TeX hyphenation dictionaries to relicense their dictionaries to be a bit more liberal, so we will ship dictionaries for some more languages

• Team status:
  • dbaron: review hell, investigating mobile text resizing
  • dholbert: CSS3 flexbox
  • matspal, tnikkel: bug fixing
  • fantasai: getting started on page-break-*

  • smontagu: implementing and unicode-bidi:isolate

Video

• Landed support for temporal media fragment URIs (e.g. http://example.com/video.ogg#t=10,20) (doublec)
  • UI piece (changes to built-in controls) still needs to land
