Awesome! Very glad to hear things are going for you with that, and happy to hear we helped narrow things down.
For finding the jQuery issue, we did exactly what you did.. just opened up your HTML and searched for 'jquery'. Then, we looked at all the instances of it, regardless of whether it was in the head or not. I've been doing this long enough that I generally know where to start investigations; you're issue wasn't terribly obscure.. we've seen many more inclusions of jQuery on some sites..
I hope that gets everything going well for you, but should you need anything else, just let us know.
Finally, if you haven't already, please consider leaving a rating and review for JFBConnect, or our support, on the Joomla Extension Directory. It certainly isn't required, but is very appreciated:

Thanks,
