Cool new features and technological additions in the 4.x Web browser include support for cascading style sheets, layering and absolute positioning, dynamic font support, the ability to make global font size changes (one of Internet Explorer's early proprietary features), inline support for PNG graphics, an integrated AOL Online Messenger client, an enhanced kiosk mode, and improved OLE support.
While internal support for ActiveX Controls is still missing, there are several third-party plug-ins available that will allow you to use ActiveX Controls within Navigator. Of these, NCompass ScriptActive and Sir Browse-A-Lot are the most notable.
Overall, while this should indeed be considered the next major release of Navigator (version 4.0), the Web browser in Netscape Communicator 4 definitely doesn't mark as revolutionary a progression as the earlier major releases of the client did. Still, Communicator definitely adds features to the Web browser that make it more user-friendly and appealing to use.
