admin-ajax return error 400 for Chrome/Edge but not Firefox

I have a bug with an Ajax request but it works on Firefox. You can test it clicking here

For Edge/Chrome I got a 400 error.

In Edge I got this error :

HTTP400: INCORRECT REQUEST - the request could not be processed by the server due to invalid syntax.

What could be the problem in my request ?

Why it works for Firefox but not for others browsers ?

Problem fixed ! The problem was not due to a browser matter. wp_ajax_nopriv_myfunction was wrapped by is_admin(). That could not work. I was logged in in Firefox and not in Chrome that´s why I thought it was a browser matter.
