Is the browser filtering extension the same as Identity shield?

I read that WAS "Identity Shield" is very good for secure banking, etc.  When I installed WAS Antivirus this morining, I saw the Firefox extension "Webroot Filtering Extension."
 
How much overlap is there, if any, between "Identity Shield" and the browser "Webroot Filtering Extension"?
 
While poking through WAS settings and the on-line user manual, I've seen "Web Shield."  Does this have anything to do with WAS "Identity Shield" and/or "Filtering Extension"?
 
I'm really interested in using WAS "Identity Shield" for shopping & banking sites.  I'm wondering how to do this with WAS Antivirus.
 
Thanks to anyione who can sort this out!
