NightShade
NightShade is a Firefox theme that I’ve updated to the newer versions of Firefox, after the author dropped support (or so it seems).
You can download it from the Firefox Addons site or by clicking here.
New update, 18/03/2010: added the much requested favicons on the bookmarks panel!
You can preview it on the Firefox Addons site.
Please post bugs here as comments.
