I'm trying to create some webapps to use with Firefox. I got an tutorial from Canonical (http://developer.ubuntu.com/resources/app-developer-cookbook/unity/integrating-tumblr-to-your-desktop/) and I didn't understand one thing, maybe someone could help me.

I have to run the following script in Web Console:

// ==UserScript==

// @name          tumblr-unity-integration

// @include       https://tumblr.com/dashboard

// @version       @VERSION@

// @author        WebApps Team

// @require       utils.js

// ==/UserScript==



window.Unity = external.getUnityObject(1.0);



Unity.init({ name: "Tumblr",

            iconUrl: "icon://Tumblr",

            onInit: null });

Everything is fine, it created the icon launcher and work with alt+tab. That enough for me by now, but, if I close the windows, the launcher icon that I created before stop working (I mean, it open the site, but doesn't work like other webapp and doesn't show in alt+tab too). Maybe I have to run this script automatically every time I enter on that site (In this example, Tumblr). How can I do that?

Thanks,
