Very pretty theme.

Also I recommend userstyle for full darkness!

For quick switch between userstyle on/off I use keyconfig and such rules:
Alt+S (switch on) Components.classes["@mozilla.org/preferences-service;1"].getService(Components.interfaces.nsIPrefBranch).setBoolPref("extensions.stylish.styleRegistrationEnabled", false);
Alt+D (switch off) Components.classes["@mozilla.org/preferences-service;1"].getService(Components.interfaces.nsIPrefBranch).setBoolPref("extensions.stylish.styleRegistrationEnabled", true);
