Might be, but that makes it easier/better to download than Mozilla FireFox. And you can choose a version with Java installed. It's 15. instead of 3.something. So there's no way that file is included with Mozilla FireFox
also, for Mozilla you still have to download plug-ins for a lot of things. Why are you going Netscape vs Mozilla?
isn't Mozilla/Netscape vs Opera more interesting (talking about IE is boring; it sucks compared to mozilla and Opera anyway
)
