Netscape 9 is not just Firefox 2 with a skin, shawnz.
Netscape and Firefox share the same technology and Gecko rendering engine (rv 1.8.1.11pre), yes, but that doesn't mean Netscape is just only a Firefox skin (not yet). Netscape 9 shares more code with Firefox, than Netscape 8 did, also true...
Both Firefox and Netscape are still different branches based upon the Mozilla technologies, they are not the same thing in a different jacket, and they are not for the same usergroup either (Firefox is more aimed at the developper-usergroup, while Netscape is more aimed at the end-usergroup). Netscape 9 is based upon what Firefox 2 uses, but that does not mean they are the same thing.
If you want Firefox + theme (like some people claim Netscape just is), you can find that
here.
(and this is exactly what they recommend people should do if they want to coninue using "netscape" after Februari)
