ReCaptcha with Ajax on Firefox

Hi,

I recently updated my Ninja forms to use Ajax calls when submitting a form – this seems to work fine on Chrome but on Firefox the ajax response in 0 / false.

This can be seem / tested here: https://www.henningswine.co.uk/contact-us/

I am running the latest ninja forms on the latest WP.

Thanks,

Harry
