I have been trying out this "Seamonkey 1.0.1 Beta" http://www.mozilla.org/projects/seam...eamonkey1.0.1/

It has the look and feel of "Netscape"...has it's own Mail Client and IRC Chat feature. Seems to perform just as fast as Firefox..has limited Extensions and Themes.

Works well...has an cookie manager/image manager/Pop up manager/form manager/download manager/password manager.
Has the java console/java script console/java script debugger/DOM inspector...it has a feature for those who lose or corrupt their profiles and forget to import, by providing remote profile storage on a roaming access server.

Overall it seems to work fine...
