best extension ever it made my day, it works great! if you're on a video already before you add the extension, you'll have to refresh but that makes sense so its not an issue at all! it is so adorable and makes your homescreen a little less boring! only downside about this is i cant focus on the video im watching because im too busy watching nyan cat! all jokes aside, this is a great extension, i highly recommend it if you want a little pop of color and fun to the boring default homescreen!
