[philipp]

• shutdownhangs with the "MEGA" addon - around 25k crash reports from 51.0.1 last week
  • https://bugzilla.mozilla.org/show_bug.cgi?id=1306838

   [shell] looks like happened after latest update enabled the MPC=true flag.  this add-on hits a known issue with the shim performance, so i requested in bug that they remove MPC=true.

• • spikes in the shutdownhang graphs end of september/mid-october & last week: https://crash-analysis.mozilla.com/release-mgmt/crash-report-tools/longtermgraph/?fxrel-bcat
  • it seems to happen once per each update of the extension, but it is widespread (~1% of users on release have it) and updates frequently
