Navigator: cookieEnabled property

navigator.cookieEnabled returns a Boolean value that indicates whether cookies are enabled or not.

The property is read-only.


A boolean.

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.


if (!navigator.cookieEnabled) {
  // The browser does not support or is blocking cookies from being set.
