Type about:customizing<enter> in the address bar. In the new window, look for the icon. When you find it, hold down the left button on it, and move it to where you want it to be. You can move any of the icons you want from here, but some icons are locked in place.

Right click an empty area of the web page. At the top of the options, you should see the arrow shaped like a circle.
