Platform/2010-Q3-Goals

General Goals

• [ON TRACK] Javascript performance near or even with Chrome 5 on their benchmarks (within 20% on SS, 30% on V8), with substantial wins on our benchmarks. (Windows, in-browser.)
• [ON TRACK] Hardware acceleration of video and other HTML and SVG content, as well as user interface, on by default for compatible hardware on all Tier-1 desktop and mobile platforms.
• [ON TRACK] Fully support the WebGL 1.0 spec, with support turned on by default in a Firefox 4 beta on platforms that support OpenGL or OpenGL ES.
• [ON TRACK] security: zero reproducible high/crit > 30 days
• [ON TRACK] Support multi-process Fennec.
• [ON TRACK] Support Jetpacks running in separate processes and never blocking the Fennec UI.

GFX

• Accelerate Firefox's in-content video and other content primitives by shipping, in a Firefox 4 beta, layers acceleration for the full Firefox window, on by default for compatible hardware on all tier-1 platforms:
  • [DONE] Windows: based on Direct3D 9
  • [ON TRACK] Mac: based on OpenGL
  • [AT RISK] Linux: based on OpenGL,
  • [ON TRACK] Mobile: based on and OpenGL ES.
• [DONE] Accelerate all drawing on Windows Vista and Windows 7, on compatible hardware, by shipping the Direct2D Cairo backend in a Firefox 4 beta.
• [AT RISK] Enhance our OpenType font feature support by shipping Harfbuzz on by default in a Firefox 4 beta on all Tier-1 platforms, with text rendering performance equal to or better than Firefox 3.6.
• [ON TRACK] Fully support the WebGL 1.0 spec, with support turned on by default in a Firefox 4 beta on platforms that support OpenGL or OpenGL ES.
  • Stretch goal: Also support WebGL on Direct3D via ANGLE.

Layout

• [DONE] Land CSS3 calc()
• [DONE] Finish and land CSS Transitions
• [DONE] Land retained layers
• [DONE] Land content/chrome rendering integration (bug 130078)

• [ON TRACK] Finish up indexGetter/Setter work for faster list[n] access in JS
• [ON TRACK] Solidify a long term plan for the future of our DOM bindings (i.e. keep hacking on XPConnect or move over to proxies)
