The WPF Plug-in for Firefox enables XBAPs and loose XAML files to be navigated to and run at the top-level or in an HTML IFRAME in the Firefox browser. An XBAP is a WPF application that can be published to a Web server and launched within supported browsers. Loose XAML is an XAML-only file that can be navigated to and displayed in supported browsers much like an XML file. The WPF Plug-in for Firefox is installed with .NET Framework version 3.5 and later.

The .NET Framework Assistant for Firefox enables ClickOnce stand-alone applications to run from the Firefox browser. The .NET Framework Assistant functions identically when installed before and after the Firefox browser. When the Firefox browser is launched and the .NET Framework Assistant is present, Firefox finds and installs the add-on. Users can configure the assistant to do the following:

• Prompt before running the application.

• Report all installed versions of the .NET Framework or just the latest version.

The .NET Framework Assistant is installed with the .NET Framework version 3.5 Service Pack 1.
