Firefox 18 with Retina MBP has issues with dropdowns


Using Firefox 18 on a 15" Retina Macbook Pro. I have my laptop retina (1440x900) set to the primary and a 24" dell U2412M (1920x1600) set to secondary. If I have a firefox window open on the external monitor, dropdowns do not show up on the external, but on the primary.

Image of the primary (with the dropdown). The dropdown should be below the address bar of the browser, instead of floating here.

Screen shot of the secondary (with the browser). Focus was in the addressbar and I started the letter 'y' and expected to see the dropdown. Instead, dropdown shows up on primary screen.
