If you have Firefox and either Microsoft Office 2003 or Office 2007, this plugin enables you to open documents directly from Office Web Apps into the appropriate Office desktop application. For example, in Word Web App, clicking Open in Word results in the document being opened in Word 2003 or Word 2007. When the document is saved in Word, it is saved back at the web location where it was opened.
Latest version of this plugin is available at Microsoft. This plugin is unnecessary for customers who use Firefox and Microsoft Office 2010.
