Okay so in older MacOS system preferences (now System Settings) there was a section where you could determine when the Mac would go to sleep or when the screen saver would come on and such. Now I cannot find it in the new layout. Right now when inactive my screen will go dark before the screen saver will come on. How can I change that? 
Also in FireFox I don't get the text correction feature like I seem to get anywhere else on my Mac. Why is that?
