I have one issue - if it is an issue, and not by design. Only applies to Firefox, and not Chrome, IE, Safari, or Opera. When I click on a popup link in Firefox, the popup opens in the other monitor. If I move browser to other monitor, popup opens in parent monitor. Is there any way to maintain Firefox popup in same monitor as parent browser?

Daniel, I had the same issue and solved it by moving the popup window back over Firefox, closing the popup window in its new location, then restart Firefox. It stays where put on mine.

Good luck.
