Here is a bunch of tests to run in your browser:

I use it for a web editor. Other than that it just sits there. I use firefox as my main browser. Problem is that firefox is a resource hog so I am in the market for something else. Maybe I will start using seamonkey

I used to use Netscape with the internal Compozer editor.

I still prefer Firefox and KompoZer - the standalone editor for webpage development.

I use it for quick changes to web pages (it has an editor built into it) but don't use it as an everyday browser. No big problems with it, I just like Chrome better.
