How to completely disable Popup Blocker in Gecko Embedded clients?

Hi,

Is there a trivial way to completely disable popup blocking
functionality in gecko embedding clients. I want to allow all kinds of
pop ups without any restriction. So far, I tried changing the values
of

private.popup.policy
dom.disable_open_during_load
dom.popup_allowed_events

but certain pop ups are still getting blocked. Since my client
controls the pages to be loaded, I don't really need the pop up
blocker functionality.
