Firefox Development

(from our goals):

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

• [NEW] Dirty profile startup within 20% of clean profile startup (modulo extensions, plugins; on windows)
  • Shawn has an updated blog post. Read it for more info.
  • Excessive cookie i/o bug bug 572223(fixed)
  • Session restore bug 582005

Platform

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

• [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.

JS

• Brendan’s patch for bug 558451 landed. Big win on v8 benchmarks. Showing a smallish Tp/Memset regression, most likely due to GC scheduling.
• ES5: 10-15 bugs. The substantial ones needed Brendan’s patch.
  • Landings
    • JSON.parse no longer permits trailing commas (also bug 582077 to keep a legacy mode for bookmarks “JSON” parsing)
    • fun.caller now throws if fun is a strict mode function
    • Function.prototype.bind implemented (see also docs)
  • Current work
    • bug 492844, bug 492845, bug 492849: extensibility, sealability, freezability ES5 methods (patch nearly done, almost ready for review, was waiting for bug 558451)
    • Implement ES5’s top-level function statement definition algorithm
• Compartments: 14 bugs left.
• JM: landing on TM tree today. Need to evaluate ARM status and debugger status.

GFX

• Beta 5 is good to go with Direct2D hardware accelerated rendering.
• This week, we will be turning on Direct3D hardware accelerated compositing of layers on all Windows platforms.
• You can test hardware accelerated compositing of layers by setting the pref layers.accelerate-all. However, there are some (huge) known issues on OS X, so we suggest you not turn it on for OS X quite yet.
  • If you run into trouble, run Firefox in safe mode – hardware acceleration is disabled in safe mode.

Layout

• bug 130078 landed
  • Some regressions; biggest issue is screen readers being mostly broken on Windows due to sniffing of our HWND hierarchy (bug 591874)
  • Known Tp regressions on some platforms because paint suppression in loading documents is effectively disabled; patches in bug 591435 will turn those regressions into wins

Content

• Remote XUL and XBL now disabled, landed for beta5 (sicking)

Tree Management

• Try What You Want
  • The TryChooser is running in production now which allows you to select the specific try builds/test/talos runs you want (as well as which platforms) in your hg commit comment. Please see documentation and give it a go! This new feature gives devs more self-serve tools, and with more people using it will save on builder cycles thus reducing try wait times.
  • If you want a test/talos suite(s) (re)triggered, please use this handy template for bugzilla with much information already entered for you

Roundtable

• usage data (PDF) supports proposal to drop OSX/PPC support for Firefox 4 [beltzner]
  • current OSX/PPC audience is pretty small
  • declining usage on older branches
  • no matching growth on Firefox 3.6
  • implication is that we’re not seeing a growing audience of OSX/PPC users, and we are seeing existing users leave that platform over time
• Anyone looking through the data collected from beta feedback via our Input dashboard? [aakashd]
  • Did you know we have daily reports on the past week’s worth of messages received with URLs attached to them? or on the past week’s worth of clustered opinions?
  • If you’re uncomfortable understanding how to search through our feedback, here’s some example searches (fyi: they all have RSS feeds)
    • Issues with Fonts
    • Issues with Firefox Menu Button
    • App Tabs
    • Issues with Direct2D
    • Issues with developer tools such as -> web console & inspect
    • issues with the addons manager
    • issues with switch to tab
    • issues with panorama (i.e. tab candy)

  • To see a list of bugs file/found due to messages received via Input, take a look at this bug query
