Mozilla PRISM Addon converts Web application as a desktop application

Prism is an application that lets users split web applications out of their browser and run them directly on their desktop.
Instead of running all your web apps in the browser, Prism lets you run them in their own window just like normal applications. A single faulty app or web page can no longer take down everything you are working on. Thanks to advances in web technology, these apps are increasingly powerful and usable. As a result, applications like Gmail, Facebook and Google Docs are soaring in popularity.
There are two ways to use Prism; A Firefox extension or a standalone application. Either way, you can easily turn any website into a Prism application.
