 This new version, more or less based on Netscape Navigator 3 Code, updated and added new features (such as support of certain CSS1 elements, minimal dynamic font support and the proprietary object element).The new suite was successful, despite increasing competition from Internet Explorer 4.0 and problems with the outdated browser core.The Communicator suite was made up of Netscape Navigator, Netscape Mail and Newsgroups, Netscape Address Book and Netscape Composer (an HTML editor, which later became Mozilla Composer and eventually was split off into a completely separate product, Nvu).
