Tried three times to install and gave up - add probably good.Foxing under consent of the king 4 many major problems from the very start and has yet to stop.Fix one and another pops up.These wall paper themes are just like previous versions that worked well.Four times I tried to install MY choice of theme and and four time the wrong theme showed up.Where's the problem in FF4 or the add-on ?
