Blocker Report

Firefox 4 Beta

Firefox Development

(from our goals):

• [ON TRACK] Feature complete Firefox 4
  • [DONE] Switch to Tab
  • [DONE] App Tabs - Scope for 4.0 reduced (non-global), near feature complete.
  • [DONE] Extension Manager - Bug list is converging, still a lot of work to do.
  • [DONE] Web Console
  • [ON TRACK] Notification UI - Geo and EM notifications done, http auth next.
  • [ON TRACK] New Theme - Windows and Mac good, Linux catching up now
  • [DONE] TabCandy Panorama
  • [AT RISK] Silent updates on Windows
  • [DROPPED] Inspector
  • [DROPPED] Account Manager - WIP patches posted, but we can't contain the review load and code risk.

• [AT RISK] Dirty profile startup within 20% of clean profile startup (modulo extensions, plugins; on windows)
  • Current status: Lots of data has been collected and analyzed, but no solid conclusions have shaken out.
  • Details page
  • Shawn has an updated blog post. Read it for more info.
  • Bugs on file that help:
    • Excessive cookie i/o bug bug 572223 (fixed)
    • Session Restore negatively impacts startup time based on the number of tabs loaded bug 582005
    • Suboptimal SQLite page size bug 416330 (fixed)
    • Provide a global VACUUM component bug 541373

Platform

(there is a team-by-team goals breakdown, as well)

• [DONE] 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.)
• [DONE] 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.
• [DONE] 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.
• [MISSED] security: zero reproducible high/crit > 30 days
• [DONE] Support multi-process Fennec.
• [DONE] Support Jetpacks running in separate processes and never blocking the Fennec UI. NOTE: jetpack team hasn't actually integrated this code yet, but it works in small test environments.

GFX

• Preliminary support for hardware-accelerated ClearType (subpixel anti-aliased text) has landed.
  • Currently only works for Direct3D 9, which is incompatible with Direct2D.
  • Pending work enables it for Direct3D 10 and OpenGL (Mac).
  • Net of this: much less frequent jaggy/gross looking text.
