Mozilla Prism has released an updated version that shows off Firefox integration:

Today we’re releasing a major update to Prism that includes new desktop integration capabilities and simpler installation. With this update, you can now get Prism simply by installing a small extension to Firefox 3. With the new Prism extension for Firefox 3, users can now split web applications directly out of Firefox without needing to install and manage a separate Prism application. Just install the extension, browse to a web app, then select Tools > Convert Website to Application.

Other new or improved features include:

• Pick an icon to represent a web app on the desktop: Prism can use the web app favicon or the user can pick a custom image to represent the web app.
• Run each web app in its own profile: Prism now places each web app into its own process/profile so they don’t interfere with each other, which also makes it possible to install a web app twice and use it simultaneously with two different user accounts.
• Badge the dock icon: Initial support for adding a badge to the desktop icon has been added. Currently, this can be done through a custom webapp.js file. We’re working on creating and reusing web standards to expose this to content without requiring custom scripts.
