Add-ons

Stability

Aurora

[marcia]

• Rel Management bot detected an increase in startup crashes in Fennec Aurora - https://crash-stats.mozilla.com/search/?date=%3E%3D2016-10-19&date=%3C2016-10-20&product=FennecAndroid&version=51.0a2&release_channel=aurora&uptime=%3C60
  • This looks to be covered by https://bugzilla.mozilla.org/show_bug.cgi?id=1308631#c8

Beta

overall rate: 1.21 (browser 1.01, content 0.19) [marcia]

• Some missing symbols for Mac on the latest beta->https://bugzilla.mozilla.org/show_bug.cgi?id=1311462

[philipp]

• no major changes since tuesday's notes: https://wiki.mozilla.org/Firefox/Channels/Meetings/2016-10-18#Beta
  • intel cpu issue, increased nvidia graphics driver crashes & std::list<T>::clear() from D2D1::EndDraw() are still the top issues in 50.0b8

https://bugzilla.mozilla.org/show_bug.cgi?id=1308863 https://bugzilla.mozilla.org/show_bug.cgi?id=1310600 https://bugzilla.mozilla.org/show_bug.cgi?id=1290403

• startup crashes:
  • (mainly) Fennec crash in nsNSSComponent::nsNSSComponent https://bugzilla.mozilla.org/show_bug.cgi?id=1301407 (#4 startup crash on 50.0b desktop last week, #2 on android)
  • Crash in Abort | LoadSheetSync failed with error 8052000b loading built-in stylesheet 'resourc... | mozalloc_abort | NS_DebugBreak | ErrorLoadingBuiltinSheet https://bugzilla.mozilla.org/show_bug.cgi?id=1303764 (#5 startup crash on desktop)
  • Crash in mozilla::ipc::MessageChannel::AssertWorkerThread | mozilla::layers::PTextureChild::SendDestroy https://bugzilla.mozilla.org/show_bug.cgi?id=1311644 (#13 startup crash on desktop, regressing in 50)

Release

overall rate: 0.93 (browser 0.75, content 0.18) [marcia]

• https://mozilla.github.io/stab-crashes/correlations.html?product=Firefox&channel=aurora&signature=shutdownhang%20%7C%20kernelbase.dll@0xcacb8 has risen on Release, doesn't have a bug associated with it. Currently #4 top browser crash in 49.0.1
  • [philipp] this is probably just a signature shift due to missing symbols for the dll file after a windows update - overall the shutdownhang rate stayed constant on release (it's at currently 0.15, which is slightly lower than during the 48 release)
