+ * "geolocation"). Only one notification with a given ID can be visible

+ * @param message

+ * @param anchorID
+ * The ID of the element that should be used as this notification
+ * popup's anchor. May be null, in which case the notification will be
+ * anchored to the iconBox.
+ * @param mainAction
+ * A JavaScript object literal describing the notification button's
+ * action. If present, it must have the following properties:
+ * - label (string): the button's label.
+ * - accessKey (string): the button's accessKey.
+ * - callback (function): a callback to be invoked when the button is
+ * pressed, is passed an object that contains the following fields:
+ * - checkboxChecked: (boolean) If the optional checkbox is checked.
+ * - [optional] dismiss (boolean): If this is true, the notification
+ * will be dismissed instead of removed after running the callback.
+ * If null, the notification will not have a button, and
+ * secondaryActions will be ignored.
+ * @param secondaryActions
+ * An optional JavaScript array describing the notification's alternate
+ * actions. The array should contain objects with the same properties
+ * as mainAction. These are used to populate the notification button's
+ * dropdown menu.
+ * @param options
+ * An options JavaScript object holding additional properties for the
+ * notification. The following properties are currently supported:
+ * persistence: An integer. The notification will not automatically
+ * dismiss for this many page loads.
+ * timeout: A time in milliseconds. The notification will not
+ * automatically dismiss before this time.
+ * persistWhileVisible:
+ * A boolean. If true, a visible notification will always
+ * persist across location changes.
+ * dismissed: Whether the notification should be added as a dismissed
+ * notification. Dismissed notifications can be activated
+ * by clicking on their anchorElement.
+ * eventCallback:
+ * Callback to be invoked when the notification changes
+ * state. The callback's first argument is a string
+ * identifying the state change:
+ * "dismissed": notification has been dismissed by the
+ * user (e.g. by clicking away or switching
+ * tabs)
+ * "removed": notification has been removed (due to
+ * location change or user action)
+ * "showing": notification is about to be shown
+ * (this can be fired multiple times as
+ * notifications are dismissed and re-shown)
+ * If the callback returns true, the notification
+ * will be dismissed.
+ * "shown": notification has been shown (this can be fired
+ * multiple times as notifications are dismissed
+ * and re-shown)
+ * "swapping": the docshell of the browser that created
+ * the notification is about to be swapped to
+ * another browser. A second parameter contains
+ * the browser that is receiving the docshell,
+ * so that the event callback can transfer stuff
+ * specific to this notification.
+ * If the callback returns true, the notification
+ * will be moved to the new browser.
+ * If the callback isn't implemented, returns false,
+ * or doesn't return any value, the notification
+ * will be removed.
+ * neverShow: Indicate that no popup should be shown for this
+ * notification. Useful for just showing the anchor icon.
+ * removeOnDismissal:
+ * Notifications with this parameter set to true will be
+ * removed when they would have otherwise been dismissed
+ * (i.e. any time the popup is closed due to user
+ * interaction).
+ * checkbox: An object that allows you to add a checkbox and
+ * control its behavior with these fields:
+ * label:
+ * (required) Label to be shown next to the checkbox.
+ * checked:
+ * (optional) Whether the checkbox should be checked
+ * by default. Defaults to false.
+ * checkedState:
+ * (optional) An object that allows you to customize
+ * the notification state when the checkbox is checked.
+ * disableMainAction:
+ * (optional) Whether the mainAction is disabled.
+ * Defaults to false.
+ * warningLabel:
+ * (optional) A (warning) text that is shown below the
+ * checkbox. Pass null to hide.
+ * uncheckedState:
+ * (optional) An object that allows you to customize
+ * the notification state when the checkbox is not checked.
+ * Has the same attributes as checkedState.
+ * hideNotNow: If true, indicates that the 'Not Now' menuitem should
+ * not be shown. If 'Not Now' is hidden, it needs to be
+ * replaced by another 'do nothing' item, so providing at
+ * least one secondary action is required; and one of the
+ * actions needs to have the 'dismiss' property set to true.
+ * popupIconClass:
+ * A string. A class (or space separated list of classes)
+ * that will be applied to the icon in the popup so that
+ * several notifications using the same panel can use
+ * different icons.
+ * popupIconURL:
+ * A string. URL of the image to be displayed in the popup.
+ * Normally specified in CSS using list-style-image and the
+ * .popup-notification-icon[popupid=...] selector.
+ * learnMoreURL:
+ * A string URL. Setting this property will make the
+ * prompt display a "Learn More" link that, when clicked,
+ * opens the URL in a new tab.
+ * displayURI:
+ * The nsIURI of the page the notification came
+ * from. If present, this will be displayed above the message.
+ * If the nsIURI represents a file, the path will be displayed,
+ * otherwise the hostPort will be displayed.
+ * @returns the Notification object corresponding to the added notification.
