The code you pasted is not a full program so I cannot test it. In
particular, I don't see the definition of editor-cookie, so I'm not
sure what it does.

The example program from the documentation [1]:

#lang web-server/insta
(define (start req)
  (define cookies (request-cookies req))
  (define id-cookie
    (findf (lambda (c)
             (string=? "id" (client-cookie-name c)))
  (if id-cookie
      (hello (client-cookie-value id-cookie))
       (url->string (request-uri req))
        (cookie->header (make-cookie "id" "joseph"))))))

(define (hello who)
  `(html (head (title "Hello!"))
          (h1 "Hello "

works for me in multiple browsers.

The only thing different I see is that you are using 'first' while I
am using 'findf'.
