This is why looking for the class of the window and the resource won't help
you as these are static anyway -- and for the class property, this is only
ever allowed to be changed when the window is in the Withdrawn state,
anyway. With firefox, they're never any different from one another, so you
can't reliably use them to uniquely identify one firefox instance from
another.
This question has come up a lot in the past -- my preferred solution
(until/if (yeah, right) things change upstream so that Mozilla allow for
some identifier as part of the WM_NAME (for instance)) is to use
IndexedWindowName, and hope for the best. It makes for some ugly style
matching, but there's ways round that if you really care.
