With current Firefox versions, you can choose to use the Firefox button menu (orange in windows; gray in Linux) at the left end of the Windows title bar, or the familiar Menu Bar like prior versions. The Firefox button is displayed by default only in Windows Vista and Windows 7, but you can turn it on/off or toggle between the two or temporarily display the Menu Bar when the Firefox button is being displayed. *See how, click here --> https://support.mozilla.com/en-US/kb/common-questions-after-updating-firefox#w_why-are-the-menus-file-edit-view-etc-missing *Other changes after upgrading --> https://support.mozilla.com/en-US/kb/common-questions-after-updating-firefox If you have selected to use the Firefox button '''''<u>and</u>''''' you use the default Tabs on Top, the Tab bar will move to the Title bar with the Firefox button '''''<u>only when</u>''''' you are in Maximize window (the middle "square" button in the upper right corner of the standard Windows application window).
