GFX

JS

Layout

• Display-list-based-invalidation is nearly complete. Planning to land after next uplift for maximum bake time. Greatly reduces the amount of repainting required on complex dynamic pages, and speeds up reflow. [mattwoodrow]
• SVG displayList conversion is progressing well now. Most test cases passing. Remaining work involves clipping paths, masks and filters. [jwatt]

• Notable Patches:
  • bug 749425 - Push the scroll frame clip inside the scroll layer so it gets transformed by the shadow transform.
  • bug 749935 - Make all nsRect Union methods saturating. If width/height overflows nscoord_MAX then clamp the x/y to nscoord_MIN / 2 and try again.
  • bug 751356 - Make presshell arena allocation methods inline and non-virtual.
  • bug 752428 - Null-check the right thing to fix topcrash.

  • bug 753742 - Force layer build on scroll frames with a displayport.
  • bug 512525 - Implement SVG Fragment Identifier parsing and animation hyperlinking
  • bug 734082 - Compute and store bounds and visual overflow bounds for both SVG leaf and container frames.

Video

• We have libstagefright audio/video decoding working on Nexus S, Galaxy S2, and Akami devices running B2G. Will land soon once some build system stuff is reviewed. Still have to figure out how to support linking to different libstagefright binaries in a single build. [eflores, doublec]
• libcubeb audio backend landed and enabled on nightly for Linux (ALSA). Windows and Mac already landed, so only Android remains. Matthew is working on software stream mixing which will make the Android backend easier. [kinetik]
• fullscreenWithKeys support has landed, along with integration with pointer-lock API. [cpearce]

DOM

WebAPI

• Started looking at implementing plumbing for security model, including "cookie jars" (or rather "data jars" since they affect IndexedDB and localStorage as well). Will not affect firefox for now, but will let us do cool things in the future in Firefox if we want to. bug 756644
• Filed tracker for "trusted apps". bug 756729
• Proximity and ambient light sensors landed on mobile.

Stability Report

Socorro

• With Wednesday's Socorro update, anyone with an admin login will be able to retrieve URLs for a signature easily directly in Socorro UI.

Desktop

Trunk

• Huge crash spike
  • bug 756796 fixed but will take some time for a crash of that magnitude to fade out of the stats.
  • Other spikes seem to be correlated to that issue - bug 756798,bug 756797
  • As bad as the spike was/is, people were putting Sunday work in to repro, get the fix done, reviewed and landed, thanks for that!
• Watching crash regressions closely over the next couple of weeks as we get close to next merge.

Aurora

• Crash rate looks pretty good - http://bit.ly/K2EmSe Tracking Firefox 14

Beta

• No new items appearing in b3 - http://bit.ly/GEI29E Tracking Firefox 13

Release

• Dealing with a number of issues relating to Flash.
  • The decision for now is to go for a variant of the blocklist we haven't done before. If you navigate to a page that is running Flash and it's an old version - we have a notification bar.
  • Adobe gave us symbols that haven't been obfuscated. We reprocessed all the reports. For the 11.2 version.
  • Still outstanding issue around 11.3 being particularly crashy - discuss in stability work week.
  • bug 686335 - mentioned in the discussion of blocklisting. Not a problem with the notification bar. Nominated as tracking for 13.

Mobile

• Great progress on crashes for beta - 9.97 crashes per 100 ADU for b2.
• Still need to bring that down but making great progress.
• Tracking top 10 list closely and more fixes pending for b3.
