While the problem is related to "GtkRange::trough-under-steppers = 1" in the theme gtkrc, let me clarify that this is a GTK widget style property, and *not* a Murrine engine option [1].
XULRunner-based applications (such as Firefox, Thunderbird, etc.) seem to ignore some (or all?) GTK widget style properties. Another property that gets ignored is "GtkNotebook::tab-overlap". In my Dichotomy theme [2] I have set the "GtkNotebook::tap-overlap" property to -1 which should have the effect of spacing tabs 1 pixel apart. This works in all applications except those that are XULRunner-based [3].
