If you are missing the Zoom In / Out buttons, it is because the said "Page Controls" are out of toolbar. Take your mouse pointer to the bottom of the page and you should see them. At the right end, there is a tiny box with dots and arrow pointing upwards. Click on that and the controls would be back on the toolbar.
