On GMail (popular email service for the 1 person here who hasn't heard), one who
has used multiple email accounts on the same machine / logged in different ways
(with and without @gmail.com) will be able to get a drop down list.  That's not
really the point here but a brief intro.

On a dual monitor setup (NVidia Geforce GO MX 440) with the latest drivers
(which for some reason doesn't add the special 'nvidia menu' in advanced which
allows the two screens to function as a really wide monitor) using the windows
"Extend my desktop onto this display" option, I get this problem.  When you
double click a field which has multiple remembered options, you get a dropdown
list of the possible selections.  The interesting thing here is, if you have the
login box on the secondary monitor and double click in it for the possible
options, they appear on the primary monitor.

I have (in the next comment) attached a PNG screenshot of just firefox on two
screens.  I have doubleclicked in the 'box' on the secondary (right) screen,
which is on the laptop, and the dropdown list appears on the primary (left)
screen, my CRT.  It appears as far right on the CRT as possible though, touching
the edge.

Reproducible: Always

Steps to Reproduce:
1. Get two screens (vital)
2. Set up video card to use two screens
3. Set up secondary screen as extension, use windows options and not special
options in nVidia or ATi tabs in the advanced section.
4. Make firefox "really wide"
5. Double click in the text box to make things drop down, make sure this box is
on the secondary monitor
6. Gasp and be amazed at lack of drop down, look at primary screen and awe in
wonder at the drop down being a mile away from where it should be.
Actual Results:  
Drop down list far far away.

Expected Results:  
Dropped down list right under the textbox like normal

I looked on other bugs and the only one that comes close is Bug 264030, and it's
far.
