USB CC Reader Not working On Firefox

[SignStop]

I have now started using Firefox (as win XP is no longer protected with IE) for my virtual terminal in my store location.

My CC reader is no longer working to capture CC numbers via a "Swipe". I know I had to enable in in IE, but I do not see a locaiton to enable that in FireFox. 

How do I enable my cc Reader for use with Firefox?
