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]

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]

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
• 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 -
• Tracking top 10 list closely and more fixes pending for b3.
