bluesky footwear complete store not functional

I downloaded the Bluesky footwear starting point and complete files. I created a site with the complete files, and the drop down forms won't function, even after I activate the dynamic dropdown extension. There are no dynamic images in any of the pages. The connection to the database was successful. I thought there was nothing needed to have the sample completed store fully functional.
Where are the tutorials to set up the BlueSkyFootwear store using the starting point files, just like there is for bluesky music.
I found the tuts for creating dynamic product options.

When I click the shoe dropdowns, I get an error message that says I need to activate the extension, but they still won't work in firefox. Could there be other extensions needed for this site to functional?
