Stop Hotmail/Outlook.live from Asking to "Add Application"

Noticed recently that the tab in Firefox with Hotmail open started displaying an 'add "outlook.live.com" as an application for mailto links?', which is annoying since it keeps coming back on every refresh.
One way to get rid of this (hat-tip to /u/xeq937 via this thread):
  • Open about.config
  • Set network.protocol-handler.external.mailto to false.
  • Refresh the hotmail/outlook tab
Haven't noticed any downsides to doing this as yet.
