I wish FF would just stop messing with this. Every time someone uses the computer, you change the theme and the bookmarks. Leave. It. Alone. What happened to the theme from FF 50? I could tell the difference between chrome, firefox and Edge or IE. Not any more. I *had* my own made up and FF destroyed it. Now I've picked this one and I'm just waiting til FF destroys it as well. Stop it. Just. Stop. With. Designer. Themes.
