Nightly

• Known issue https://bugzilla.mozilla.org/show_bug.cgi?id=1461459 continues to be at the top of crash stats. Interesting that are no Linux crashes, only Mac and Windows
• philipp's comment resuscitated https://bugzilla.mozilla.org/show_bug.cgi?id=1464938 - Crash in AsyncShutdownTimeout | profile-change-teardown | Extension shutdown: @testpilot-addon
• 2 year old Core | XPCOM build has risen up - https://bugzilla.mozilla.org/show_bug.cgi?id=1276488, although many more crashes than installs
• Core Panning & Zooming bug https://bugzilla.mozilla.org/show_bug.cgi?id=1457603 is still visible on the latest nightly. Should it be assigned to someone for investigation?
