First, let me say this is not that big a deal, I'm just a bit curious about the following.
I don't know if I'm just doing something stupid with Fire Fox, but for whatever reason my Head Case toolbar bookmarks (the drag-able ones) always loose the HC favicon after visiting another site that has favicons. Same deal with regular old folder bookmarks.
So if I go to Headfi from Headcase, my bookmark reads 'Head Case' but features the Headfi favicon.
Usually coming back seems to replace it again.
As far as I can tell this doesnt happen with my other bookmarks. If it does, it is far less frequently, as I have never noticed it.

I don't know if its just me, or if everyone experiences this. Just curious is all. I'll rough it if need be.
