What toolbar are you using? Some toolbars you can create your own button on. On the URL address bar (top of your screen where it says https//....etc), see the ? logo for akaQA. Left click on it and hold, then drag it to your toolbar. Release it when you see a tiny + sign appear on the edge of it. Otherwise, if that does not work,  just google the toolbar you had that has the akaQA button on it and download it to the computer you are now using.
