-  // onRefreshAttempted will be fired before onLocationChange.
-  // When a refresh is caused by a <meta> tag in the document,
-  // onRefreshAttempted will be fired after onLocationChange.
-  //
-  // We only ever want to send a message to the parent after
-  // onLocationChange has fired, since the parent uses the
-  // onLocationChange update to clear transient notifications.
-  // Sending the message before onLocationChange will result in
-  // us creating the notification, and then clearing it very
-  // soon after.
-  //
-  // To account for both cases (onRefreshAttempted before
-  // onLocationChange, and onRefreshAttempted after onLocationChange),
-  // we'll hold a mapping of DOM Windows that we see get
-  // sent through both onLocationChange and onRefreshAttempted.
-  // When either run, they'll check the WeakMap for the existence
-  // of the DOM Window. If it doesn't exist, it'll add it. If
-  // it finds it, it'll know that it's safe to send the message
-  // to the parent, since we know that both have fired.
-  //
-  // The DOM Window is removed from blockedWindows when we notice
-  // the nsIWebProgress change state to STATE_STOP for the
-  // STATE_IS_WINDOW case.
-  //
-  // DOM Windows are mapped to a JS object that contains the data
-  // to be sent to the parent to show the notification. Since that
-  // data is only known when onRefreshAttempted is fired, it's only
-  // ever stashed in the map if onRefreshAttempted fires first -
-  // otherwise, null is set as the value of the mapping.
