I really like this theme. The colors, and the light and dark contrast are perfect for my Firefox browser. (tip) The butterfly animation can be activated easily when you push the menu button, and then the customize button. Then exit the customize window.
This theme is so nice and dark with a hint of something alive to keep me company on-line. Why do my butterflies stop moving once I start browsing??? Such a shame, otherwise I'd give 5 not 4 star-rating, eh? Keep up the great work!
