What is Mozilla?
Netscape 6 is not based on the code from Netscape 4. Instead the developers decided to start over from scratch and develop completely new code that would be as compatible as possible with the web standards. At the same time they decided that they would take advantage of the world's programmers by producing an open source version of their browser. This open source version is called Mozilla.
The fact that Mozilla is open source means that anyone who can program can download the source code for the browser and create their own modified version that adds the features that they want. They can then make their modified version available for others to use. Those modifications that prove popular and useful will eventually find their way into the base version of Mozilla and perhaps from there into a subsequent version of the Netscape browser.
The Netscape browser is based on Mozilla but again there are differences with features that have been both added and removed compared to the open source version. When selecting your web browser you might like to consider the Mozilla browser as an alternative to the Netscape one, the differences are relatively minor so it probably comes down to personal preference.
