Foxfire 2.0 The Darker Side

Foxfire has been touting its 2.0 update for a couple days now. I just downloaded it and ran the install program...when what did I see? A message box saying:

"Foxfire cannot install the Onfolio extension".

Back to version 1.5 for this webboy. Fortunately, I didn't see anything in 2.0 that I was dying for.
