Prism from Mozilla Labs lets you convert any web application into a desktop accessible program, complete with its own icon and dedicated screen. Why would you want this? Well it makes it easier to access some types of web apps if you can use them in their own space, without having them displayed in a generic browser. Things like docs, control panels, accounting services, even web mail.
Google Chrome has this feature and I love it, I immediately made Gmail into a desktop app so I could fire up my inbox without having to run up a full web browser instance. Very cool. The Prism product is implemented as a Firefox addon, which is superb (you’ll find it under the Tools menu when it’s installed) and you can set the app to run minimised from the task bar, start automatically and display pop-up notifications. Excellent. A keeper.
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. In the future, we will be releasing web app bundles from the Prism developer community that let you customize your application to use many of the operating system features common to a desktop application.
