What information was incorrect, unhelpful, or incomplete?

"A cookie with the Secure attribute is only sent to the server with an encrypted request over the HTTPS protocol. It's never sent with unsecured HTTP (except on localhost)"

Do you have anything more you want to share?

I'm not sure if MDN documents bugs or broken implementations on certain platforms, but I'd assume this falls under Browse compatibility. I'd also change it myself but I'm not exactly sure how these are supposed to be formatted.
