Looks excellent, but... Rated 3 out of 5 stars
...it seems to have an issue with links in the address bar. When I hover over a link, the address bar current website disappears and does not show me where the link leads. Also, the new tab button is iffy. I'll have to give this 3/5 stars instead of 4/5, because this theme seems buggier than the default one. (Though it may just be Firefox 4's fault. >_<)This review is for a previous version of the add-on (18.104.22.168.10).
