Important Note Before You Start:
Google is actively phasing out third-party cookies in Chrome through its "Privacy Sandbox" initiative. As of 2024–2025, some Chrome versions no longer allow you to fully unblock all third-party cookies in the traditional sense. Instead, you have two options:

Critically, complete unblocking is impossible in standard Chrome builds without enterprise policy overrides or feature flags that Google marks as “temporary” or “unsupported.” Below are instructions for both scenarios
