I just spent one and a half hours looking for my perfect Firefox theme header (i.e., "add-on"). When I saw MaDonna's Sleeping Fairy I knew this was the one! But I noticed that many themes that appealed to me were created by MaDonna. I LOVE her add-ons! When it comes time to rotate my theme, I will definitely choose from one of MaDonna's many beautiful creations — but it won't be easy!
