I got the same thing with Safari and FF on OS X, then I remembered that I have blocked just about every backchannel between web pages and FB that I could find. Are you using something like an AdBlocker script to block Facebook Connect or an extension like Facebook Disconnect? When I turned that stuff off, I was able to import a few hundred contacts...
