When users hit the Facebook send the button goes gray but the FB dialog does not display. Other social media buttons work (Twitter, Pininterest, Linkedin). Works fine in Chrome. FB Like works.

In Chrome & Safari. works correctly, bringing up the FB dialog. Just not in Firefox.

This is with Easyblog 3.9.14976 on Joomla 2.5.14
Problem happens in Firefox 25.0

See http://www.wcwonline.org/WCW-Blog/Latest, and the attachment showing the Settings/Social Integrations/Facebook page in the backend.

Thanks for your help!
