Netscape 7 (final) has been released today. Compared with Netscape 6.2, this new version offers tabbed browsing, print preview, and full-screen mode (among other new features).
Of course, all of those features have been in Mozilla for ages ;). In fact, there’s little reason to try Netscape 7 (based on Mozilla 1.01) when Mozilla 1.1 is now available.
