Why do ad blockers no longer work in Chrome?

Many users are noticing that their standard ad blockers suddenly stop filtering ads in Google Chrome, letting invasive ads slip through or causing constant playback errors on popular video streaming sites.

The technical migration to Google's Manifest V3

The issue stems from Chrome deprecating the Manifest V2 API used by legacy extensions. AdBlock Network has been natively architected for Manifest V3. The program performs read-only asynchronous requests to multiple independent endpoints to keep the firewall updated, processing local rules via the Advanced layer without relying on Chrome's obsolete engine.
