Stability Report


  • Fennec 10.0.3esr (current release!) now supported well by recently added ESR support.
  • Socorro now generates correlation reports for new Firefox versions 14.0a1, 13.0a2, 12.0 in addition to the 3 crashiest ones, which include current releases.
  • Only small fixups in tomorrow’s incremental release, as the big target now is to get ElasticSearch working ASAP.
  • If you have any specific issue you want solved in Socorro next quarter, please tell KaiRo about it.


  • Nightly – FF14
    • Top crashes appeared in single build then disappeared – bug 736507
    • bug 736761 – crash in mozilla::image::DiscardTracker::EnableTimer.
    • bug 736947 – OOM crash in mozilla::safebrowsing::HashStore::ReadHashes
    • bug 736944 – crash in nsAccTreeWalker::NextChildInternal @ nsIFrame::IsGeneratedContentFrame
    • bug 736695 – crash in nsGenericElement::UnbindFromTree , when I open Customize Toolbar with Video DownloadHelper 4.9.8 installed
    • bug 736815 – crash in js_ValueToBoolean – not a new signature but appearing in a bit higher volume on trunk.
    • bug 736830 – crash in js::types::TypeMonitorResult – reproducible
    • bug 704124 – Firefox Crash @ gfxContext::SetSource – reproducible
    • All Reproducible top crashes
  • Aurora – FF13
    • Just started shipping updates so better data in a couple of days.
  • Beta – FF12
    • bug 736524 – bug only appearing on Beta. It is now resolved.
  • Release – FF11
    • Some concern about Flash hangs but not sure if higher volume than normal. The fix that bsmedberg worked on for VS2010 doesn’t work in FF12 and FF11. For FF13 things should be fixed.
    • bug 722044 – add touch bad memory to skip list. This bug is blocked on a decision of which skip list to implement. Kairo is going to go through all the skip list bugs and make sure they are actionable.
    • bug 733892 – some concerns about this rising. Marcia going to work on trying to reproduce based on comments in the bug.
