Drop-down lists at the bottom of a page do not show all options.
Firefox made an update going from version 15.0.1 to 16.0.1 that has caused an issue with our site (www.dataforma.com). The update caused a drop-down list that displays at the bottom of the page to only show the first option, and does not display a scroll bar when you have the page on a second monitor or auto-hide your taskbar on your primary display. If you do drag the window to your primary screen that has a taskbar and click on the drop-down, the list will appear will a scroll bar. You can also move your mouse into the list that displays “lock” and use your scroll-wheel to scroll up and down the list. I am sure that we are not the only webpage that has been affected by this bug. This needs to be fixed ASAP because our clients cannot access key functionality in our system using your updated version of Firefox. Thank you.

I can't see it -- this is after you log in?
Just to clarify, does the problem occur on a single monitor system in any configuration, or is unique to a two-monitor display?
This is after I log into our database. This happens in many of the pages in our system where there is a drop-down list in the bottom-left portion of the page. It happens when the browser is displayed on a secondary monitor where there is not a taskbar at the bottom of the page. This also happens on a single monitor system that has the "Auto-Hide Taskbar" option selected. I have attached the image with the bugged list and an image of how the list should appear. The list appears correctly, as in the second example, when you restore the page and drag the window up from the bottom of the screen. Thank you for your help.
Where there is insufficient space below the control, Firefox usually flips the list up above the control (as in the attached from the forum advanced search page). But perhaps that isn't true if the control is in a frame or otherwise constrained.
Can you show what that control looked like in Firefox 15? You could use a "portable" edition to capture the screen shot. Note that both should not be running (or cannot run) at the same time.

Does it help if you disable hardware acceleration ?
