Alaska USA recommends using Firefox instead of Netscape browsers.
Netscape abandond development of their version 4 browsers which are incompatible with UltraBranch.
Netscape subsequently released Netscape versions 6-8, based on different code that supports modern internet standards. Netscape no longer develops browsers and the technology behind their newer browsers forms the basis of Firefox.
Without active support for potential security problems, Alaska USA cannot recommend Netscape browsers.
