I recently installed Mozilla's latest browser Firefox. It's a fairly light weight browser but so far it has performed very well. At 4.7 MB it worth taking a look at. http://www.mozilla.org/products/firefox/
My main beef with Mozilla (and Netscape) in that past has been inconsistant printing. The fonts have always been ugly. Not with this latest brower! All our internal apps that only printed properly in IE print perfectly in FireFox.
