Add-ons

https://bugzilla.mozilla.org/show_bug.cgi?id=1280125 - New Flash plugin block live today (there are reports that the new flash version causes more unresponsive plugin warnings in firefox: https://support.mozilla.org/en-US/forums/contributors/712040 )

Stability

We have a fair number of startup crashes that seem related to McAfee: https://bugzilla.mozilla.org/show_bug.cgi?id=1131180 and https://bugzilla.mozilla.org/show_bug.cgi?id=1277897. And a fair number of startup crashes that seem related to COMODO: https://bugzilla.mozilla.org/show_bug.cgi?id=1274630 - should this bug be highlighted to someone for a block decision?

• we have a plan to improve testing on that. no ETA but we are discussing about that

Aurora

48.0b1:

• persistent startup crash in NS_InitXPCOM2 https://bugzilla.mozilla.org/show_bug.cgi?id=1262731 is the top score crasher; at 1.13% (was over 10% at the start of the cycle)
  • icudt56l.dat file missing from the program folder
  • should probably be considered blocking 48 until we really know what's going on there

• startup crash in je_free | js::ctypes::CData::Finalize https://bugzilla.mozilla.org/show_bug.cgi?id=1131180 with mcafee siteadvisor is 0.41% <- higher than that if we sum the crashes from bug 1277897
• shutdownhang in mozilla::net::nsHttpConnectionMgr::Shutdown https://bugzilla.mozilla.org/show_bug.cgi?id=1279163 is 8.7%
  • needs backout of bug 698882 on 48 as a fix
