I always used this add-on and wished it looked like the screen shot. I don't like the color bar all the way across the screen I preferred just the tab the new approach is too distracting. I had customized colors for my commonly used sites but it doesn't appear that the new version allows this. Random colors are not helpful. Also when only the selected tab is colorized and have to read the tabs rather than just selecting a color. Hopefully it will improve but for now bye, bye
