Apple Safari completely blocks third-party cookies, first in common browsers

Apple's web browser, Safari , upgraded on March 24, 2020 (Tuesday), now completely blocks third-party cookies by default. This version upgrade is due to the enhancement of

'Intelligent Tracking Prevention (ITP)' which is one of the security functions included in Safari, and Safari is the first browser to completely block third-party cookies in common browsers.

Third-party cookies enable 'cross-site tracking' to track the movement of users across different sites. Introduced to Safari in 2017, ITP is a feature that protects the privacy of users, and gradually added a function to block third-party cookies.

Apple has enhanced ITP features with this Safari upgrade and has completely blocked third-party cookies by default. This will not only prevent

cross-site request forgery attacks, but also prevent Internet advertisers and others from using cookies to track user behavior between different websites. Except for the Tor browser, which is rarely used for general purposes, Safari is the first browser to completely block third-party cookies.

It has been announced that support for third-party cookies will be abolished within two years for Google's ' Chrome ', which is commonly used in Safari, and ' Edge ' developed by Microsoft.
