Rated 5 out of 5 stars
...very nicely done.
My browser looks much better and I can more easily view tab content with ColorfulTabs.
My thanks and compliments to the designer.
It may not be possible but I would like to suggest a new option for ColorfulTabs that would apply the tab color to the background of the URL address field. So the background color of the URL field would change to match the color of the active tab. I think I may find the URL color cue as the easiest way to identify the active tab.
