Can you make the rest of the top part black as well?

Actually the whole theme is plain black. It is the Firefox 57 that changed the color on the lower part on the way it is designed. Others have mentioned this, too. Until Firefox 57 changes the way that part of the browser is designed, I can't do anything about it. Thanks for the 4 stars, anyway.
