Prism the Web Application Launcher
A lightweight version of Firefox for using RIA on the desktop
Prism, formerly Webrunner, installs Web applications on your desktop, on
Windows, Mac, Linux.. This is a small version of Firefox dedicated to Web
application as Analytics or others. An interface between the desktop on your
operating system and the Web.
Each application is physically represented by a bundle, a file that creates
the link between Prism and the remote software.
What is Prism?
We can read in the press: "Webrunner, Firefox for a single Web site". In fact the exact opposite is true. It is an interface that avoids to launch Firefox to use a single website! And we have an interface for each site with an icon on the desktop, thus avoiding any further navigation on the site, and it allows to keep the environment of each Web application.
How to use Prism?
Actually everything is in the installation. Once the application is installed,
it becomes an icon on the desktop on which one click, as with any application
installed on the computer, with the difference that we must be connected to
let it running.
It is not complicated to use, rather than installing software on the computer,
Prism is installed and a bundle for an application. We then take advantage
of all updates without any subsequent installation since that is done on the
server.
- Download Prism in the version for your system (Windows, Mac, Linux) and run the program.
- Download the bundle that interests you (see at Mozilla on the link at
bottom). Store it in the Prism directory.

- From Windows Explorer or any equivalent program for your system, click on the downloaded file, with a .webapp extension.
- In the lower right corner of window there is a gear that opens a menu, click on "Install to desktop".
- Give a name for the icon. Your application is installed.
Thereafter, a click on the icon launches the application in a window dedicated to it, without toolbars and buttons as on the browser.Your login and passwords are stored for an immediate access.
Other features of Prism
As a streamlined version of Firefox, the Prism container removes many features. However, in addition to immediate access to Web applications, the software adds:
- A direct print function from the menu of Prism.
- Support for the download manager.

Building his own bundle
The bundle is represented by a .webapp zip file containing an INI file as
of any XUL application, and an optional JavaScript file.

gives instructions.
