Netscape X

Netscape Navigator 9.0 is a browser-only release. It does not contain an e-mail client, newsgroup reader, or HTML composer.

Users of the Netscape 7.x suite may choose not to install Netscape Navigator 9 to avoid the loss of these features. You can have the best of both worlds by keeping Netscape 7.x installed for mail and news and installing Navigator 9 for browsing the Web.
