duplicate of [/questions/1274577] thread. When you move your mouse cursor on the tab area to select a tab, it happens quite often that the Mac menu bar opens automatically and covers the tab area, thus preventing you from opening the tab (see the screenshot). This is a rather inconvenient issue with Firefox for Mac. For example, in Chrome for Mac, there is a vertical gap on top of the tabs to avoid this effect - see the screenshot. Or in Safari, tabs are located below the address bar. Is there any solution to the issue?
