ESPN360 Plugin

ESPN360 requires a plugin similar to Flash. This worked for me.

1. Save the xpi as a zip (http://player.movenetworks.com/pub/D0295F3F/qmp07103010.xpi).
2. Extract npmnqmp07103010.dll and nsIMNQMP.xpt to \PortableApps\FirefoxPortable\App\firefox\plugins. Ignore the extract paths that are in the archive.

Hope this helps.
