How to remove all Firefox wallpapers for start page that are included? I want my start page black but all you have are other colors, abstract, etc. These wallpaper choices are stored somewhere inside Firefox 135. I want to remove them all. Also after searching from Firefox start page, the background turns an ugly navy blue. Here would be a great example of where solid black would also look better. So how do you make both of these pages display only black, white or gray? With NO other options or clutter. I do not want to see any other colors or designs one of your interns picked out.
