Hi Frank, where was the button before? If it was a bookmark, that bar might be hidden. 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 Bookmarks Toolbar, Menu Bar, or other bars, click it on the list. Was that it? If you don't have any toolbar area at all, check whether your Firefox is in full screen view. The F11 key switches back and forth between regular and full screen.
