The AddonUpdateChecker is used to download and parse update information for an add-on's update manifest. If all you care about is finding the newest version for an Addon
then you probably want to use findUpdates()
instead.
To import the AddonUpdateChecker, use:
Components.utils.import("resource://gre/modules/AddonUpdateChecker.jsm");
