After clicking ''add to cart'', captcha doesn't appear with chrome and edge, only with firefox; why?
I tried to clear cache, delete cookies, reset browsers, but nothing.
Are you using any proxy or VPN service? Try disabling it... that sometimes interfere with the captcha.
I've been having the same problem:
