The answer that has been marked as correct doesn't answer
your question so it follows your question is different in which
case a new thread is best.
I just pointed Firefox 2 at a webhelp setup and saw no such
message, it never did apply to Firefox, also I don't see any dummy
window, not sure what you are referring to.
It sounds like this may be to do with the way the help is
called. Try opening some webhelp yourself pointing to the start
page. If what you see is correct, that supports the theory that the
call is the problem.
