As of 1 February 2008, technical support ended for the Netscape browsers. For more information, read the 28 Dec 2007 announcement posted on the Netscape blog at https://forums.spybot.info/showthread.php?24329-End-of-Support-for-Netscape-web-browsers.
AOL’s focus on transitioning to an ad-supported web business leaves little room for the size of investment needed to get the Netscape browser to a point many of its fans expect it to be. Given AOL’s current business focus and the success the Mozilla Foundation has had in developing critically-acclaimed products, we feel it’s the right time to end development of Netscape branded browsers, hand the reins fully to Mozilla and encourage Netscape users to adopt Firefox.
Please bear in mind that no active product support will be available.
