Firefox Developer Tools

Add-on SDK


  • This week's Snappy summary
  • Kyle landed a very significant Snappy fix this week as part of memshrink that reduces leaks in chrome (bug 695480). It should significantly reduce memory usage and thus cycle-collector pauses, etc.
  • Patrick landed a change to have Firefox now hedge bets and warm up a TCP connection while checking the cache (bug 729133). More details on Patricks’s blog.
  • Work going into improving setTimeout (bug 743877, bug 715376).



  • FIXED: bug 750424 nsXULPrototypeNode::Release should add itself to the purple buffer. This was blocking bug 735099 Re-enable incremental GC


Fennec and other bugs:

  • bug 728284 - Main container layer has siblings that are drawn in the background
  • bug 732016 - Maple: scrollIntoView does not clamp to the page size
  • bug 728983 - Maple invalidation problems with scrollable layer and multiple div's
  • bug 706193 - footer text on inflated too much
  • bug 708175 - Form controls with fixed width or height shouldn't have their text inflated
  • bug 745780 - update harfbuzz code to upstream commit
  • bug 746975 - update graphite2 library to 1.1.2 release
  • bug 745580 - handle bad results from Core Text shaping more robustly.
  • bug 706194 - Adapt and check in tests from webkit for new unicode-bidi attributes
  • bug 279330 - Midas hilitecolor command only works in CSS mode
  • CSS Working Group meeting in Hamburg next week.
  • Hoping to land GPU-accelerated clipping to border-radius today bug 716439. Fixes various performance problems with scrolling inside elements with border-radius, and canvas/video with border-radius. Some big changes. (ncameron)


  • Landed MediaStreams infrastructure on mozilla-central (roc). Currently the only exposed APIs are mozCaptureStream/mozCaptureStreamUntilEnded on media elements and the ability to set MediaStreams as the src of media elements, so you can route video/audio from one media element to another. Not that useful by itself, but a foundation to build other APIs on (getUserMedia, WebRTC, audio/video processing) etc. Next step is to land some processing functionality.
  • Not video, but Nick is going to land a patch to disable attempts to remove our exception handler that triggers breakpad. This may reveal latent crashes.








  • Accessibility engine is now built by default on Mac FF nightlies so that we can widen testing for ~5 weeks. We may revert for Aurora.

Tree Management

  • upcoming downtime while moving ftp.m.o/stage/surf to scl3
    • RelEng getting access today, will start verification
    • needs 5+ hours
    • needs tree closure *and* also blocks us doing releases.
    • tinderbox will also be offline during this time
  • possible ride-along moving graphserver
