  <p>How to make the console of the Firefox DevTools multi-line?
  I am aware of the <kbd>Shift</kbd>+<kbd>Enter</kbd> keyboard shortcut, which makes the command line go to the next line. Though like in Firebug, I want to vertically separate my console into command line and results part, but I can not find that functionality.</p>
