You get the orange Firefox menu button when the menu bar is hidden. *Firefox menu button > Options *View > Toolbars (press F10 to display the menu bar) *Right-click empty toolbar area See also: *https://support.mozilla.org/kb/how-do-i-get-firefox-button *https://support.mozilla.org/kb/Menu+bar+is+missing Current Firefox versions only show the "Tabs on Top" menu entry in the "View > Toolbars" and "Firefox > Options" menu and in toolbar context menus if the tabs aren't in the default position on top. If the tabs are on top and the menu entry isn't available and you want to move the tabs below the navigation toolbar then you need to toggle the browser.tabs.onTop pref to false on the about:config page.<br /> A Firefox restart is necessary to update the menu entry to either show or remove it. *http://kb.mozillazine.org/about:config
