Pull up Firefox and press the F10 button. A menu will appear at upper left. Choose View, then choose Toolbars. If Roboform has disappeared altogether (which shouldn't be), you will have to reinstall it. This is done from the same menu, choosing Tools, then Add-Ons. Remember: if you don't see the menu, and you don't like dealing with the three horizontal bars "menu" at the upper right, always press F10 to post a classic menu.
