* Adds a new popup notification.
*
* @param browser
* The <xul:browser> element associated with the notification. Must not
* be null.
* @param id
* A unique ID that identifies the type of notification (e.g.
* "geolocation"). Only one notification with a given ID can be visible
* at a time. If a notification already exists with the given ID, it
* will be replaced.
* @param message
* A string containing the text to be displayed as the notification header.
* The string may optionally contain "<>" as a placeholder which is later
* replaced by a host name or an addon name that is formatted to look bold,
* in which case the options.name property needs to be specified.
* @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.
* - source: (string): the source of the action that initiated the
* callback, either:
* - "button" if popup buttons were directly activated, or
* - "esc-press" if the user pressed the escape key, or
* - "menucommand" if a menu was activated.
* - [optional] dismiss (boolean): If this is true, the notification
* will be dismissed instead of removed after running the callback.
* - [optional] disableHighlight (boolean): If this is true, the button
* will not apply the default highlight style.
* If null, the notification will have a default "OK" action button
* that can be used to dismiss the popup 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.
* persistent: A boolean. If true, the notification will always
* persist even across tab and app changes (but not across
* location changes), until the user accepts or rejects
* the request. The notification will never be implicitly
* dismissed.
* dismissed: Whether the notification should be added as a dismissed
* notification. Dismissed notifications can be activated
* by clicking on their anchorElement.
* autofocus: Whether the notification should be autofocused on
* showing, stealing focus from any other focused element.
* 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).
* hideClose: Indicate that the little close button in the corner of
* the panel should be hidden.
* 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.
* 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.
* name:
* An optional string formatted to look bold and used in the
* notifiation description header text. Usually a host name or
* addon name.
* @returns the Notification object corresponding to the added notification.
