I run a smart board in my classroom through my MacBook Pro. When I open Firebok, I can only get Firefox to open on the extended desktop. It will not open on my main screen. The only time i can get Firefox on my main screen is to disable the extended desktop or drag it over to the main desktop.

Try to disable hardware acceleration in Firefox.
