Is it possible to make clear buttons be always on? It is somewhat annoying to see when they appear and disappear.(I changed CSS myself).PS. Also, is it possible to include more imaginative colored icons? For example: http://findicons.com/icon/235501/edit_clear?id=348445 http://findicons.com/icon/202947/edit_delete?id=348401

Questa recensione riguarda una versione precedente (1.3.1-signed.1-signed) del componente aggiuntivo. 

If you install the addon within FF 4.0 with the addon manager the version will be correct, also in FF4 the icon will not disappear.
