nsIDragDropHandler is an interface for communicating with the built-in drag and drop implementation in the content area. Use this to register where the listeners should attach (something that implements nsPIDOMEventTarget which is what we end up using under the hood).

void detach();
Parameters

None.

hookupTo()

Attaches drag handlers to a specified receiver, setting up callbacks to let built-in behaviors be overridden.

void hookupTo(
   in nsIDOMEventTarget attachPoint,
   in nsIWebNavigation navigator
);
Parameters
