We don't see any support email from you so we can't look up your account and tell you the exact reason you got the captcha, but it isn't new. You'll get the captcha for various reasons, including IP address and if you do a large amount of searches in a short amount of time. One thing to try is to log out of EF and close all EF browser tabs (or try from a private browsing session) and see if you still get it. If you need further help please email us directly.
