reCAPTCHA won't even try to work if your UserAgent isn't on Google's short list[1] of supported browsers. If they don't like your browser, the reCAPTCHA widget simply gives up with a fatal error[2]. Any new browser, browser variant, or browser-like tool cannot access any website that requires reCAPTCHA. Same for anyone obscuring their UserAgent or using an older browser for any reason. reCAPTCHA is de facto restriction against any new competition in the browser market.
