bizarre Facebook connect with authlogic problem

I set up a Facebook connecе to my application following the http://github.com/holden/authlogic_openid_selector_example. But I have a st开发者_Python百科range problem with Facebook Connect on Firefox and Google Chrome browsers, it just will not allow me to authenticate. But on Safari it works perfectly.

Is your development platform accessible to Facebook? In my experience, Chrome and Firefox did not work with that example on my local machine behind a router, but Safari did (just like your experience). However it all worked when the setup was on an internet-accessible box.
