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). * 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. * 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.
