Fx only. Works for me, see the pics: Vista HP/Aero/Fx default theme. Needs my Transparent ( glass ) Firefox 4* - Black Mica. Inclided: Addons Compatibility reporter, BBCode, BBCodeExtra, Biscuit, CheckPlaces, Clipple, Clippings, ColorZilla, Converter, CookieCuller, DragIt, Extensions List Dumper, Flagfox, gTranslate, Greasemonkey, ImageTweak, Lazarus, Linkification, Menu Editor, Multiple Tab Handler, OptimizeGoogle, Quick Java, Quick Translator, Rainbowpicker, Status-4-Evar, Tab Utilities, Text Formatting bar, Textarea Cache, Textsaver, Undo Detach Tab, Update Notifier. CustomizeGoogle has not been updated for a while now, use OptimizeGoogle instead. I don't use some of this exts. and have no idea how their prefs dialogs look with this style now. If you see problems, start a discussion and i'll see what i can do.
Expanding on pile0nades' idea (http://userstyles.org/style/show/369); this should remove virtually all the jerkiness of the greasemonkey gui and makes it a little bigger.
