NIS 2013 (20.2.0.19) & Identity Safe & Firefox 17.0.1

Happy New Year!

 

New issue/problem since the mid-December patch update.

 

In Firefox - ID Safe NOT working when a second (or more) Firefox window is open.  The very first browser window recognizes a saved web site and fills or offers to fill the id and password.  Open a new, additional browser tab or separate window, and ID Safe does NOT recognize the (regular, saved) site as one that can be filled.  Nothing. Vault open - but no "Fill Login Fileds" offered.  This is a departure from past NIS versions - and very frustrating.  If the first browser window remains open, it does continue to offer fills - but any and all subsequent open browser (Firefox) windows - no action.  Chrome is fine - it works there with multiple Chrome windows open.  Please advise.
