You can check the height of the menu bar.
You can use code like this as a start:
const {classes:Cc,interfaces:Ci} = Components; var wm = Cc["@mozilla.org/appshell/window-mediator;1"].getService(Ci.nsIWindowMediator); var wd = wm.getMostRecentWindow("navigator:browser").document; var mb = wd.getElementById('toolbar-menubar'); alert(wd.defaultView.getComputedStyle(mb,"").getPropertyValue('height'));
