     <b>Note:</b> With "document_idle", content scripts may not necessarily receive the <code>window.onload</code> event, because they may run after it has
     already fired. In most cases, listening for the <code>onload</code> event is unnecessary for content scripts running at "document_idle" because they are guaranteed to run after the DOM is complete.
