Issue with N360 v20 and FF

Hi, I am running a pc on Win 7 64-bit with N 360 v20.1.1.2 and Firefox 15.0.1. I can save passwords using Norton Toolbar  2013.1.1.4 but I can not edit or sort them using the Edit Cards because it doesn't display stored entries. It is empty. I can only see these entries using All used cards.
