add-ons for tracking threatFollow

From comments here and there, it sounds as though they exist. Do they? If so, what are some of the better ones?

Thanks for any help.

I'd suggest visiting both only through use of Firefox with NoScript and AdBlock enabled, as there have indeed been incidents in the past in which sites have been hacked and their ads turned into delivery systems for keyloggers(I believe this happened to worldofwar.net once).
