Cloudflare is using the Google recaptcha service. This failure happens on /fallback which returns a 400 with "Sorry, an error has occurred" in the body. For example:
https://www.google.com/recaptcha/api/fallback?k=6Lfmzf4SAAAAAESlOdWAUnRh3ab4BcteAbBBXsFm&hl=en&v=r20160216085053&t=0&ff=true returns 400 and this body:
<!DOCTYPE HTML><html dir="ltr"><head><meta http-equiv="content-type" content="text/html; charset=UTF-8"><meta http-equiv="X-UA-Compatible" content="IE=edge"><title>reCAPTCHA challenge</title><link rel="stylesheet" href="https://www.gstatic.com/recaptcha/api2/r20160216085053/fallback__ltr.css" type="text/css" charset="utf-8"></head><body><div class="fbc"><div class="fbc-alert"></div><div class="fbc-header"><div class="fbc-logo"><div class="fbc-logo-img"></div><div class="fbc-logo-text">reCAPTCHA</div></div></div><div class="fbc-message fbc-main-message">Sorry, an error has occurred</div><div class="fbc-separator"></div><div class="fbc-privacy"><a href="https://www.google.com/intl/en/policies/privacy/" target="_blank">Privacy</a> - <a href="https://www.google.com/intl/en/policies/terms/" target="_blank">Terms</a></div></div><script>document.body.className += " js-enabled";</script></body></html>
/fallback is called only after the browser has failed to meet the requirements and OrFox fails "we support the 2 most recent versions" of Firefox.
but why the fallback captcha fails as well is not clear ...

there is a test url on a related tor ticket (https://trac.torproject.org/projects/tor/ticket/16096) - https://www.google.com/recaptcha/api/fallback?k=6LeIxAcTAAAAAJcZVRqyHh71UMIEGNQ_MXjiZKhI
Orfox has no problems with this one .. But when called from cloudflare it doesn't work ..
