Title:
  HUD Service high CPU usage with Firefox

Status in The Application Menu:
  Confirmed
Status in Unity:
  Confirmed
Status in “firefox” package in Ubuntu:
  Invalid
Status in “indicator-appmenu” package in Ubuntu:
  Confirmed

Bug description:
  When using HUD to access Firefox menus, it will use a high amount of
  CPU (around 70%), even after Firefox is closed. It looks like its
  trying to index Firefox menus (speacially the bookmarks menu, that has
  a lot of entries).

  Steps to reproduce:
  - You need a Firefox install with hundreds of bookmarks.
  - Start Firefox
  - Start the Hud and try to search a item that it's on your bookmarks menu.
  - See the high CPU usage of unity-pane-service and hud-service.
