Rated 4 out of 5 stars
Still the best dark minimalist theme, except in Fx 10 it renders the add on page unusable for me.This review is for a previous version of the add-on (4.0.5).
Best Theme -And thank I God for eyes to see it Rated 5 out of 5 stars
This is the BEST theme ever in my opinion, both in compactness (important) and beauty, though the Colorful Tabs extension helps also. This also has been updated to work with FF5, and i have tried others but they place a large space below the tab row if you go beyond 4 rows. With the TabMixPlus extension i can choose multiple tab rows, and the width of tabs, resulting in about 20 fairly identifiable tabs per row across my 19'' monitor .

The next best theme is DarkOrange, but you can hardy see the scroll bar handle. Keep up the good work~
