Yes, but several other browsers are available for Linux, such as Arena, Chimera, Lynx, Mosaic, and RedBaron, so why limit yourself?
If you must have Netscape, the current version is Netscape Navigator Gold, version 3.01. If you’re downloading over a 28.8 connection, go have a cup of coffee while you wait. If you want to listen to music and news from around the world over the Internet, you can also get the RealAudio 3.0 Player for Linux. Unfortunately for TV junkies, a version of RealPlayer isn’t available for Linux just yet.
