The most recent versions of the Navigator browser comes in two flavors. One version is just a single component of a large package called Netscape Communicator , which includes email, net news and various other more esoteric applications such as a program to write web pages and Internet scheduling. The other is just the web browser stripped out so it can stand alone. Unless you really want to use Netscape's web-based mail or news reader, I'd stay away from the bloated Communicator and just take Navigator. Navigator runs fine in less than ten megabytes of RAM, while Communicator doesn't seem really happy with less than sixteen.
Navigator is big, and is getting more complex to configure with every new release.
From the viewpoint of a new user, Navigator has a bewildering collection of choices for handling extensions, helper programs and display options. Version 4.7, which was recently released, has even more features. There's no doubt that if something can be done on the Web, it's probably Navigator that can do it. But most people don't need all its bells and whistles. If you have the resources, Navigator is a solid program with much to recommend it.
