When opening a new private window, it appears in a different position from the existing window, at the top of my screen. This I don't like. I would like the new window to appear in exactly the same position (and size) as the existing one (basically on top of the current window). Is there some way to make this happen by tweaking FF options? Thanks in advance for any help with this. 1 week later: no replies? Really? Nobody has any idea how to fix this?
