Stability Report


  • Incremental release on Wednesday will not bring much new, some admin UI cleanup.
  • Work is continuing on rapid beta support.


  • Support for WebRT crashes is working - low ADU right now. Separate product in crash stats.

Flash 11.3.300.265

New Trunk crashes

  • bug 774632 crash in js::GetObjectParent
  • bug 774357 crash in nsHTMLMediaElement::EndMediaStreamPlayback


B2G / Firefox OS

  • First B2G crash report sent while ted is working on getting Breakpad fully working (bug 761909).
  • Finishing up sending the reports is marked for blocking Basecamp (bug 773892) but requires someone to work on that.


  • Highlights
    • B2G Testing is going to be taking more of my time
    • Jelly Bean, Cyanogenmod quitting and the onPrepareOptionsMenu crash bugs are the ones to watch for release
    • Aurora is more unstable than Nightly; Chances are that this initial beta will be unstable comparitively and it would be nice to fix some of these issues before we release in beta.
    • more libxul signatures in nightly. Will be investigating correlations in why this is occurring.
    • Beta has a bunch of flash crashes listed in the top 10 bugs : bug 732059, bug 759109, bug 732059, bug 750217, bug 758259

Mobile Web Compatibility

  • Mobile Web compatibility is about more than making the mobile Web work on Gecko
    • Evangelize the use of techniques that work across browsers such as detection of "Mobi" in UA string
    • ...but all of our testing is performed with Firefox on Android and Firefox OS
  • Four compatibility issues
    • UA sniffing - sending Firefox the wrong site
    • Webkit prefixed CSS in use that Firefox doesn't grok
    • Webkit specific functionality (typically JS)
    • Gecko limitations such as unsupported CSS properties and performance issues
  • We are working on a variety of tactics to tackle these issues
    • Evangelism to the Web dev community on how to develop mobile sites that work in non Webkit browsers
    • Site specific investigation and outreach to report issues and work to get fixes
    • Ditto for Web frameworks ^
    • Automated discovery of potential UA sniffing and CSS issues
    • Changes to our platform
      • Unprefixing CSS properties
      • Investigation into aliasing select Webkit CSS prefixes
      • Significant performance improvements made by Layout team


  • Mac OS X builds on Nightly will be switched to use Clang today (bug 733905) [ehsan]

Build system overhaul
