Freecorder with Ffx portable

Hi.

There is that software called 'Freecorder' that lets you record streaming music

http://www.applian.com/sound-recorder/

Apart from the installer, it also has an optional .xpi toolabar for ffx. It also works with ffx portable as long as i'm using the latter on my PC (where Freecorder is actually installed).

But when i use ffx portable elsewhere, the toolbar is still here but there is no installed version detected obviously.

So i was wondering if there was a way of putting the Freecorder program files on a usb drive (w/o any modifications) and make ffx portable detect it like it was 'installed' on my drive

Thx
