Netscape 8.x

Netscape 8.0 is the eighth major release of Netscape, released in 2005. This is the first version of Netscape to be based on Mozilla Firefox, in this case being version 1.x, and is as such compatible with add-ons, plugins and themes designed for it. However, it does no longer ship with an e-mail client, a newsreader, a composer and a address book, leaving only the Navigator.

This version is notable, as it can use both the Gecko engine of Firefox and the Trident engine of Internet Explorer on Windows. It also comes with two new themes, called "Winscape" (which is the default one and more resembles Firefox) and "Fusion".

Instead of using the previously used GRE Setup to install Netscape (which was also used by Firefox at this time), Netscape was installed using the NSIS install system, which was later also incorporated into Firefox starting with version 2.0.
