How do you change the wallpaper behind the Firefox Toolbar? I set it to Despicable Me, now I want to change it and can't remember how I did it!
I got a pop-up a while ago to change the wallpaper behind each of the toolbars. There were a ton of choices and I thought it would be fun to have Despicable Me. Now I am tired of it and can't find out how to change it to something else, even back to default.
