Multiple Monitors with Firefox default

[OrangeSVTguy]

I use Firefox on a second display and every time I restart, it's always on my main display. How can I keep it on my second monitor when I start up? ML lacks Spaces so I can't assign programs to certain screens any more.

Anyone have any tips?

I run 3 NEC Flatscreens on my MacPro 3.1 and just upgraded to ML from Snow Leopard last week. Every time I restart the computer all my icons on the left screen get transferred to the right screen. Never had this problem in any previous OS going back to 1990 and I have always run 3 monitors.

Also every time I drag an attachment from Mail onto the Desktop - you never know where it will end up? Just have to go searching monitors.

ML apparently has not been tested on multiple monitors in everyday use?
