Where do you get the firefile.php file? Rated 3 out of 5 stars

Where do I got to download the:

firefile.php

file? I've downloaded the add-on. And I have no idea where the files are going.

This really should be covered in the installation notes. :o(

This review is for a previous version of the add-on (0.8.8.1-signed.1-signed).
