Gecko 1.9 implements full-page zooming. Mozilla Firefox exposes this functionality in the user interface through the “View → Zoom” menu and allows zooming by holding down “Ctrl” and pressing + or - or by scrolling the mousewheel up and down. The zoom levels that the user can change to were limited to the ones specified in this preference.

This preference was renamed to toolkit.zoomManager.zoomValues.
