Question

My drop down options menu is transparent. Why is this happening & how do I fix it?

Ever since I've upgraded to Firefox 19 from 18 none of my drop down menus work, they're all completely transparent as you can see in the following screen shot: http://i.imgur.com/PvKyZ6K.png

It's this way in every field in which drop down options appear, including the awesomebar (which is the most annoying).
