Hi Dorothymac, it's easy to hide the classic Menu Bar. Is that what happened? To turn different bars on and off, you can use one of these methods to show the toolbar list and select the desired bars there: * right-click a blank spot on the tab bar (or the "+" button) * tap the Alt key to activate the classic menu bar > View > Toolbars * in Customize mode > Show/Hide Toolbars (see: [[Customize Firefox controls, buttons and toolbars]]) To turn on the Menu Bar, Bookmarks Toolbar, or other bars, click it on the list. Was that it?
