The code you display above does little: what you say is: create a
window, and if it is created, destroy it. I don't believe that is what
you want.
Simply take the onOpen handler of the PWC window that is opened (there
are samples on the website) and let it close (any other) windows that
are open.
Or, if all you want to do is display a new website contents, just
replace the contents of the currently open window.

This is a bug in Firefox, not in PWC. Popups are blocked by means of
user settings, far beyond the reach of any javascript. If, however an
IFrame contains popups, Firefox thinks it is "trusted" (which is quite
ok, but not completely so), and allows popups. PWC uses IFrames (there
is no other way) q.e.d.
If you want popups blocked properly: stick to Opera, the only browser I
know of that brings popup blocking to the next level.
Technically it is possible (depending on security settings of the user)
to override the javascripts contained in websites contained in IFrames.
However, I doubt there is very much of use case for this (and it is very
complex to block popups this way, if not next to impossible, and
definitely not feasible).

I suspect a script on the website that you are calling, which is able to
identify that it is loaded inside a frame and automatically breaks out
of it. Again, out of your reach (or you must call the guys of the other
website).
