Firefox - displaying web notifications from extension/addon

Question

I'm building Firefox addon (with addon-SDK) and I'd like to display desktop notification to a user. There is Notification object but it doesn't seem to work from addon code (background page). There is no error etc, but no dialog for permissions is displayed, so no notifications can be displayed. I've tried of course adding permissions/desktop-notifications but no effect.

Edit: pasting sample code I've tried (the code is located inside callback function for socket.io event. Event is received properly, but no notification is displayed, or request for permission.

        Notification.requestPermission( function(status) {
        console.log(status); // notifications will only be displayed if "granted"
        var n = new Notification("title", {body: "notification body"}); // this also shows the notification
    });

I've also found alerts service this one works. However alerts disappear quite fast (too fast for me) - edit: that's the way it works - so guess no code sample needed, as I don't see any option to make them last longer.

Is there any way to display chrome like notifications on Firefox? (chrome.notifications.create) Or at least use web notifications object from within the addon?

If you're using the add-on SDK, you're looking at the wrong docs. Here are the notification docs.

You create a notification like so:

var notifications = require("sdk/notifications");
notifications.notify({
  title: "Jabberwocky",
  text: "'Twas brillig, and the slithy toves",
  data: "did gyre and gimble in the wabe",
  onClick: function (data) {
    console.log(data);
  }
});

All the docs you look at should be a subset of developer.mozilla.org/en-US/Add-ons/SDK.
