I used to use Netscape 4.x. Netscape used to be my favourite browser up until about sometime in 2001.
This new version is heavy and bloated browser. It also installs other unwanted programs like the Weather Channel software, and I find it to be slower than other browsers based on the same engine like Mozilla.
The features are wonderful, and pages display properly or according to standards. You can quickly select between an IE view or a Netscape view. I think this browser is important for developers, but end users don't need this commercial browser which is owned by AOL, and updates to the Netscape browser have been officially discontinued.
