In example Mozilla has very clearly implemented OS theming instead of ... just providing a packaged theme that could be disabled. Here is one style sheet that serves utterly no useful purpose:
chrome://ctraddon_os_special/skin/tabsontop_offextra.css
I'm really not interested in, "not sure", "you can't" or "you shouldn't do that because of I-didn't-reseach-but-I-have-an-opinion" responses. I'm interested in cleaning up the GUI so my clients and I can get work done.
