Yes it happens in Firefox 14.01 , Ubuntu 12.04 64-bit , Kernel 3.2.0.27.29 , Unity 3d.
Apart from Drop-Down Menu , it also disables my RIGHT-CLICK menu in Firefox , nothing happens on right-clicking .
On continues Right-clicks it shows a tranparent Right-click Menu's Rectangular Border and nothing else.
Upon restarting Firfox this problem vanishes , but using Ask-ubuntu lens again triggers this behaviour. Restarting Firefox seems to be current workaround.
