Problem loading Deckbox using Firefox

There seems to be a problem loading Deckbox using Firefox.  I have been able to access my inventory through Explorer as well as by using the Dolphin Browser on my NOOK, but am unable to access in my usual way through Firefox.  Is this a known issue, and is there a fix on the way?  I recently acquired a lot of cards from the early '90s, and would like to add them to my inventory in the near future.  Also, is there any chance of a Deckbox app being made available for NOOK?
