Feed not appearing in footer in Firefox only

Hi

I applied a number of updates to plugins including to 1.9.4 of Custom Facebook Feed.

Unfortunately the feed is now now showing in Firefox (28.0) in the footer of the website:

http://www.bimskitchen.com

However, it appears correctly in Safari (7.0.3) and Chrome (34.0.1847.116).

Can you help please?
