Disable cross domain tracking in Safari

Some websites use third-party content providers. A third-party content provider can track you across websites to advertise products and services.

With this option turned on, tracking data is periodically deleted unless you visit the third-party content provider.

How to fix it

macOS 10.14 - 14

  1. Open Safari > “Preferences” > “Privacy”
  2. Enable “Prevent cross-site tracking”
