Don't know about the rest of youse, but the crystal ball is in the shop so I'd need just a tiny bit more information. Like what the relevant CSS and HTML look like. The word "theme" normally makes me think CMS with a bunch of built-in styles, but here you seem to be talking about brother's browser themes. FF and That Other Browser can't share themes can they?
