Comparison shot Chrome vs Firefox 29:
While they are similar, Chrome is a lot more angled while Firefox is more smooth. Also, non-active tabs are handled way differently, Firefox has a search bar and a disappearing forward button, and the menu is way different. Pretty much all modern browsers use basically the same UI with a slightly different look because it's small, unintrusive, intuitive and it works. Thoe only thing making this more Chrome-like than the older is the menu button that's in the same place and the same icon and the new rounded tabs.
