Comment (by gk):

 After talking with ahf a bit I think we can do something smarter. We could
 require OCSP-must-stapling for .onions and otherwise just prevent it.
 Firefox is supporting it since ESR 45 at least:

 https://blog.mozilla.org/security/2015/11/23/improving-revocation-ocsp-
 must-staple-and-short-lived-certificates/
 https://tools.ietf.org/html/rfc7633

 Dbryrtfbcbhgf: The button is not necessarily the issue. The OCSP request
 goes as already out when you are requesting the domain.
