Just heard about this from a friend of mine and since I know of more than a couple of fellow FF users on here, I figured I'd pass it along.
Trojan.PWS.ChromeInject.A is a Trojan that registers itself as 'Greasemonkey,' a well-known collection of scripts that add functionality to Web pages rendered by Firefox.

Trojan infection can occur via drive-by download or download duping according to several websites.
