Personally, I love the current Firefox.com design and see the simplicity as a feature. And it's designed to be responsive to any screen size. A design like this would have been incredibly challenging to build with CSS 2.0 in 2008. That's the point of this post. But if you find the design boring, just like the CSS Zen Garden, you can design your own user stylesheet to re-style the whole site, hundreds of pages in dozens of languages, into any design you want, with one stylesheet, because the styles are cleanly separated from the markup. Have fun!
