NightShade
NightShade is an updated version of the Firefox theme RulerDark.
Currently, I’m waiting until Firefox 4 final is there, and you can expect a update to this theme with an unique new look quite soon after the final release!
NEW UPDATE: Version 1.1, submitted 18/03/2010 – Enables the favicons in the bookmarks panel.
