Huh interesting. I immediately had a positive reaction to the name because of this. Love Firefox. already loved Calckey err I mean Firefish though so I suppose I am not objective.
It really conveys the open and user control centric nature of the project. An homage to the fox. You have now not just the fox but the fish with which you can tame the raging fires of the web. Fish makes more sense than fox too cause the web is like an ocean. Idk just thoughts
