New tab popular sites.
Actually Opera with their Speed Dial was first with that (you can manually define which sites to use, but it's basically the same feature). Then similar extension to Firefox was made. So Chrome wasn't first to get this.
Opera had download manager in 1998, years before first version of Firefox showed up.

Also IE9 has now new logo:
