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'));

A good place to ask advice is at the MozillaZine Extension Development forum

The helpers at that forum are more knowledgeable about web development issues.
