• [ON TRACK] html5 parser on by default in a beta.
• [ON TRACK] Out of process plugins for the Mac on by default in beta.
• [ON TRACK] TBD% reduction in empty-xul-window gecko initialization time.

GFX

  • Layers implementations based on OpenGL and OpenGL ES; and
  • Direct2D support, turned on for at least some subset of hardware. (This depends on RelEng - bug 549120!)
• Improve CSS3 font support by implementing Harfbuzz for simple scripts on Tier-1 platforms in a developer preview, and creating a CSS3 font test suite.
