Navigator: cookieEnabled property
navigator.cookieEnabled
returns a Boolean value that indicates whether cookies are enabled or not.
The property is read-only.
Value
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 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.
Examples
js
if (!navigator.cookieEnabled) {
// The browser does not support or is blocking cookies from being set.
}
