So with you on the lack of good Firefox themes. I've always used Qute, the original Firefox default from back in the day -- it's the least cluttered and in my opinion the most appealing. But in recent versions, it's introduced these ugly horizontal divider lines between the various toolbars that you can't get rid of. (I guess now you can edit it yourself, but I'm not as code-savvy as I'd like to be.)
