My screensaver option is not in use. It must have happened the last update. Where do I go to turn it back on?

Going black when not in use is your screen saver and what you want, right?

This would not be Firefox but part of your operating system. Check your power options in your status bar (battery/AC, and power plan), and in the windows control panel.
