- IE can't load it, because it doesn't have good enough support of HTML5 and modern web standards.
- FF has horrible resizing of images (https://bugzilla.mozilla.org/show_bug.cgi?id=517294)
- Chrome has horrible font rendering (maybe it's only when there's shadows). See the text on the right of this particular website.
- Safari has horrible chrome and isn't a windowsey application. But at least the website looks right!
