Until and unless I see clear signs of Mozilla behaving at Google's behest, I'm not going to worry.
Google wants strong competition in spaces where they don't make money (in fact this is how all well-run corporations operate)... so throwing some pocket change at one of their "competitors" in the browser space is very good for their business (it keeps other competitors like Microsoft busy).
Google even mentioned (I remember this from 2003 or so) they want competition in their profitable areas (search) since being a monopoly is a) soul-damaging and b) invites government regulation.
