Mozilla is all set to release the first beta version of their web-to-desktop platform “Prism,” and take the wraps off new website. The updated version includes several new features, like tray icon and notification support, and application-specific settings such as fonts and proxies. You can also choose a custom icon. To roll your own Prism apps, you'll need either the Firefox extension or the Prism application (which is portable). You can download both from Mozilla's getting started page.
