I don't know who told you that, but they're wrong. In Unity, Firefox (and globalmenu-extension) have no control of the positioning or view of the menus. This is entirely controlled by the shell, and this is explained in the bug reporting guidelines (https://wiki.ubuntu.com/MozillaTeam/Bugs) which we ask everyone to read before submitting a Firefox bug.
This needs reassigning to the correct component, but I'm 99.999% certain that this has already been reported anyway
