 <p>
 Like browser actions,
 page actions can have an icon,
 a tooltip, and popup;
 they can't have badges, however.
 In addition, page actions can appear and disappear.
 You can find information about icons, tooltips, and popups
 by reading about the

 You make a page action appear and disappear using the
 $(ref:pageAction.show) and
 $(ref:pageAction.hide) methods, respectively.
 By default, a page action is hidden.
 When you show it, you specify the tab
 in which the icon should appear.
 The icon remains visible
