FireFox, once the champion of no-fat slimmed down focused design, has now become bloated. On my I7, it now takes almost 5 seconds on a warm start, and consumes over 100 megs of RAM, with just a few tabs opened.
What good is features, if all they do is getting in my way?
That said, it is a very good stable full-featured browser, and Mozilla is doing wonders for the Web.
