I made a comment about this in a similar vain: Mozilla wants to overload the Firefox name to the point where it's totally meaningless. The success of the Firefox name is no doubt the reason but this fails to recognize that's not how names work. This direction is exactly the reason why Nintendo called their console "WiiU" and that turned out about as well as this ultimately will.

There is absolutely nothing wrong with Firefox being the name of a single product. The entire underlying premise of this redesign is flawed.
