Hmm, it is easy to control whether to show the Menu bar, either via the right-click context menu or via customize, but there is no way to hide the Navigation Toolbar where the controls you mentioned are normally positioned. Can you confirm you lost the Navigation Toolbar that also has the location/address bar is no longer present or is this about other toolbars like the Bookmarks Toolbar that also can have controls on them ? Are you possibly using code in userChrome.css to hide the Navigation Toolbar that is no longer working properly ? *https://www.userchrome.org/what-is-userchrome-css.html Start Firefox in <b>Troubleshoot Mode</b> to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if <b>hardware acceleration</b> or <b>userChrome.css</b> is causing the problem. *switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Themes *do NOT click the "Refresh Firefox" button on the Troubleshoot Mode start window *https://support.mozilla.org/en-US/kb/diagnose-firefox-issues-using-troubleshoot-mode *https://support.mozilla.org/en-US/kb/troubleshoot-extensions-themes-to-fix-problems

Thanks for your help.
