I really think its a lovely background but I dont have the firefox version that this could work on :( I want this really bad! I love blue ^.^This review is for a previous version of the add-on (15.0.21.08.12).
Well why don't you install a newer version of the browser? Which version of Firefox are you using? Previous versions of the theme support Firefox 3, 3.5, 3.6 as well.
