Navigator: cookieEnabled property

Note: When the browser is configured to block third-party cookies, and navigator.cookieEnabled is invoked inside a third-party iframe, it returns true in Safari, Edge Spartan and IE (while trying to set a cookie in such scenario would fail). It returns false in Firefox and Chromium-based browsers.

Note: Web browsers may prevent writing certain cookies in certain scenarios. For example, Chrome-based browsers, as well as some experimental version of Firefox, does not allow creating cookies with SameSite=None attribute, unless they are created over HTTPS and with Secure attribute.
