If you are a Firefox user but you like the interface style of Google Chrome, Chrome Frame is the best choice for you.
Chromin Frame is a Firefox add-ons that developed by Zero Fire, it places the tab bar at the top of window, and replaces the title bar and window frame bringing it closer to the Chrome look. Chromin Frame does not depend on any particular theme, however, you could choose Chromifox theme to give your Firefox a completely Chrome look.
