Homepage constantly refreshes after adding Facebook Login button

I just added the Facebook login button to my site and it refreshes the page every second.

This happens on FF but not Chrome or IE.

H开发者_运维知识库ere is the home page: http://comehike.com/

Any idea why this might be happening?

Here is a test page that has the problem: http://www.comehike.com/index_alex.php

You're calling FB.login() called before calling FB.init()
