Toolbars & E-mail window layouts......
Here's the address bar where you type in web addresses. You can also see the "Links" bar for your most used favorites (explained on the Internet Intro page).
If your address bar disappears, click the view menu and if there is not a check mark next to address bar (or other part) click it and it should re-appear.
Remember all toolbars can be dragged out of place. If all the items are checked as to the left image, then sometimes re-arranging the browser desktop will reveal the long-lost address bar.
