Netscape's web browser was once dominant in terms of usage share, but lost most of that share to Internet Explorer during the first browser war. The usage share of Netscape had fallen from over 90-percent in the mid 1990s to less than one-percent by the end of 2006.

Netscape is credited with developing the Secure Sockets Layer Protocol (SSL) for securing online communication, which is still widely used, as well as JavaScript, the most widely used language for client-side scripting of web pages.

Version 3.0 of Netscape (the first beta was codenamed "Atlas") was the first to face any serious competition in the form of Microsoft Internet Explorer 3.0. But Netscape easily remained the number one browser for the time being.

Netscape also released a Gold version that incorporated JavaScript, RSA security and an Apple Inc. QuickTime decoder.
