Selectively unblocking popups in Safari?

Some knucklehead constructed a Web site so that it works in a popup
window. I have Safari set to block popups, so the site is unuseable.
Firefox allows me to allow popups from selected sites, and I'm unable
to find a way to do that in Safari? Am I going to have to use Firefox
for this site and not Safari?
