Custom Icon in the URL of NN7

I've noticed, recently, that NN7 has a custom icon that loads to the left of the URL... any idea how to create something for that, considering Netscape Dev won't give me any info?

Not a big deal, purely cosmetic, just wanted to know:
1. How to do it
2. Is this something I'm going to see more often in new browser extra junk that I should probably do just to say I can:D

It is a favorite icon, the same thing that IE supported in the past is now supported by the newer gens of NS.

The instructions for getting it to work in IE are identical for getting it work in NS7+.

Ahhh!!

Thank you Feyd -- you rock:thumbsup:
