Bootstrap/Jquery form with paypal, Firefox issue - cross domain

I've got a web form that submits the results of the form to me and redirects user to paypal to pay... it works great. Except in firefox... In Firefox, it redirects to paypal, but the results of the form are never sent to my email. Looking at the developer console, it is an xmlhttp problem with paypal being a different domain... I have tried installing an SSL cert so that it wasn't going from non secure to secure for PayPal, that didn't work. I have two files, [login to view URL] and [login to view URL], they are both attached. What I need is the user to fill out that form, and when they click the paypal button, it will email me the results of the form, and let them pay with paypal. If this existing form can be fixed, then great, or if you have a different way of accomplishing this task, thats fine as well. Most important, form needs to stay and be in bootstrap website. And it must work in all browsers.
