Rated 5 out of 5 stars

It's a pity, read what Arvid Axelsson wrote on his webpage:
"It’s time to finally end my theming efforts. I have no plans to update my themes for Firefox 4 or later. Reasons for this include a better default theme, a lower number of users of my themes and a large amount of work required just for maintenance. Thanks to everyone who has been using them."
