If you just want scrollbars to test the look of having a bar, try setting the overflow property:

body { overflow:scroll; }

This will force Firefox to display a scrollbar for your window. For a vertical bar only, use overflow-y instead:

body { overflow-y:scroll; }

This is the best way to force scroll bars.
