Examples

In this simple example we add a listener to the notifications.onClosed event to listen for system notifications being closed. When this occurs, we log an appropriate message to the console.

browser.notifications.onClosed.addListener(function(notificationId) {
  console.log('Notification ' + notificationId + ' has closed.');
});
