=============================================================

AsyncShutdownTimeout 	

{"phase":"profile-change-teardown","conditions":[{"name":"Extension shutdown: [e-mail]","state":{"state":"Startup: Run manifest"},"filename":"resource://gre/modules/addons/XPIProvider.jsm","lineNumber":2211,"stack":["resource://gre/modules/addons/XPIProvider.jsm:startup/<:2211","resource://gre/modules/AsyncShutdown.jsm:observe:541"]}]}

=============================================================

these crash reports are spiking up in volume after the rollout of monitor in november. they are primarily hitting users on 63.0.1, where the signature is accounting for a whopping 33% of all browser crashes during the past couple of days.

numerous user comments in crash reports are indicating that the crash is taking place during firefox update from 63.0.1 to 63.0.3:

from the comments it's unclear if the update is ultimately succeeding or if the affected users might get stuck on the old firefox release after the crash.

a similar pattern already took place during the first rollout of monitor in september - after each new firefox dot-release the async shutdown timeout reports were spiking up for the prior version (see attached screenshot).
