Firefox swaps my monitor display when opening/closing

When I open firefox, my two monitors (left one is primary, right one is secondary) swap roles. (Ie, right one is main, left one is secondary and instead of moving the mouse between the two, I have to move it off the far right end to go to the secondary monitor)

When I close it, everything reverts back to the way it should be. I've tried re-applying my monitor settings both in nVidia Control Panel and in my windows screen resolution settings.

I'm using Windows 7 Ultimate 64-Bit (Legal licence - so no cracks or anything stuffing around).

System: CPU: i7 Graphics: 2 x Geforce GTX285 running SLI Memory: 6gb DDR3 Triple Channel Plenty of free hdd space.

Hopefully this is enough information to help you. Until then - I'll keep watching my monitors switch roles :)

Thanks Clifton Kent

Nevermind, I figured out the problem.

I use a program called Ultramon to display a second taskbar on my other monitor and quite a while ago I had set custom display properties in Ultramon for firefox (namely to display it maximised on monitor 1) - Once I disabled these custom settings it stopped swapping my monitors around.
