Indeed, Mitchell Baker of Mozilla has commented that the concept of EULA was at first considered necessary for Firefox, but may be pointless now. He isn't talking about disposing of a EULA altogether, but rewriting the existing one, in such a fashion that they feel everybody will be happy with it. Of course, one of the big complain that users are having is that a FOSS browser like Firefox shouldn't need to have any sort of EULA to begin with.
Personally, I see little need for an agreement to use a browser that is pitched and offered as completely free anyway. It's Mozilla's choice, and I hope this time they will side with the users.
