Notices / Schedule

  • MSVC 2010 today.
  • Firefox 10 shipping today (rrrt@mozilla.com for broken websites)
    • If you see any fallout, please notify rrrt@mozilla.org (Rapid Release Response Team)

Firefox Development

  • New Tab Page (bug 455553): Little bit of a bumpy landing, but it’s landed now, still preffed-off by default. There are several followup issues to fix, but we think it’s ready to enable by default on trunk, and so we’ll do that after the merge.
  • Line breaks in tooltips (bug 358452): long standing HTML spec compliance issue, now FIXED for Firefox.
  • Silent update
    • Add-ons default to compatible ships today in Firefox 10
    • Windows UAC service rides the train to Aurora

Firefox Developer Tools

  • Firebug 1.10 is restartless and lazily initialized.
  • Page Inspector in general release Firefox 10
  • (inaudible) Initial Debugger UI and Protocol landing SOON

Performance

  • Snappy is transitioning from identifying issues to fixing issues. Good stuff coming.
  • CC + GC are the most well-known causes of pauses in Firefox. Olli is landing huge cycle collector improvements (half of the patches landed so far), bug 705582, bug 717500. If that doesn’t solve all CC problems by Tuesday, Andrew is standing by with bug 710496 to limit how often CC can run. These improvements have a good chance of showing up in Firefox 12.
  • about:jank indicated that laggy sessions are primarily caused by our direct2d accelerated drawing code, bug 721273. Turning off graphics acceleration made things a lot less slow (Options/Advanced/use hardware acceleration). It you experience lots of lag in your sessions (on youtube, blogs with high quality backgrounds, etc) please try about:jank. This requires running a very recent nightly.
    • Install the extension, go to about:jank, browse around, then refresh about:jank. In the case of gfx lag, DrawThebesLayers shows up on top.
  • Benoit’s profiler works well on Mac now, Windows support may be as early as this week.
  • Telemetry histograms should now survive restarts (so we can do shutdown telemetry, etc), bug 707320.
    • edit: this had to be backed out due to startup crashes. 🙁
  • Working on session restore issues this week.

GFX

  • bug 720428 – Quartz canvas should be lots faster in today’s build.

JS

Layout

  • No update

Video

  • Nothing to report

DOM

  • New DOM bindings starting to take shape. A group of DOM team members met in Paris last week to start up the third and largest stage of the new DOM bindings work. This work is being tracked here

WebAPI

Services team working on support for “remote events”. I.e. ability to get notifications even if you’re not on website.

Network

  • Networking team is in SF this week, drop by and say hi if you’d like.
  • Working to deploy node.js to test machines so we can land SPDY automated tests. This is the last thing we need to do before we try enabling SPDY by default.

Identity

Identity work will see Mozilla storing user data on Mozilla servers, so it’s important to highlight these two posts (by Mitchell and Ben, respectively):

Spec for BrowserID DOM API is well under way, ready for feedback from DOM/WebAPI team:

Plugins

  • Bug 90268, content ownership of plugins, should land today.

Mobile

  • ICS plugin support is waiting for a mozconfig update to land. Should be in for tomorrow’s nightly
  • tile painting is in on trunk
    • it is a regression in terms of checkerboarding ATM
    • will uplift to aurora and beta when the regression is resolved
  • final decision for UA String has been made (for 11) after many gyrations

Accessibility

  • Nothing to report. (A11y work progressing well on many fronts)

Tree Management

  • No updates
