Datepicker broken in Safari and Firefox

I’m having an issue of the datepicker and reCaptcha not working on my form in Safari and Firefox. It works exactly as I want it to in Chrome.

Additionally, the client requested that weekends not be selectable. I’m not a Javascript expert, but I was able to remove weekends by adding the code snippet from Gravity Form’s documentation to the bottom of the js/datepicker.js file. I reverted to the old JS file to see if it would resolve the issue, but it did not.

I also noticed that a testimonial slider isn’t working in Safari or Firefox as well. I wonder if the issues are related.
