An easier way to adjust thumbnail size is by using the Ctrl +/- shortcuts. (That's Ctrl with the plus and minus keys--but only the top row keys will work; for some reason you can't use the plus and minus keys on the numeric keypad.) These shortcuts increase (plus) or decrease (minus) the number of columns shown on the screen. But, unlike the slider, it perfectly adjusts the size to make maximum use of your screen space. It also happens to be the same shortcut for increasing or decreasing magnification (zoom level) in the Editor.
