Wow that is really nice. I would suggest you make the picture a data: uri rather than a link. I modified it to do so. Now it is much faster. Looks great!
I believe the offending code is the '//Autohide menubar' line. Unless you know something I don't, that can't/won't affect it. // is not the proper comment for CSS. Try /*comment here*/ instead.
Wow, lots of those were neat. I didn't like the overall effect that the style made, but many of the scripts were useful, and they went together. I especially liked the transparent tabs and the one that made the menu bar smaller.
