AddonUpdateChecker

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 Addon.findUpdates() instead.

To import the AddonUpdateChecker, use:

Components.utils.import("resource://gre/modules/AddonUpdateChecker.jsm");
