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.
You need to register at the MozillaZine forum site in order to post at that forum.
