Starting June 2024, adblockers such as uBlock Origin and many other extensions on Chrome will no longer work as intended. Google Chrome will begin disabling extensions based on an older extension platform, called Manifest V2, as it moves to the more limited V3 version.
“Security”, haha yeah right
An extension having access to everything on every page you visit is a potential security issue.
Whether that’s an acceptable risk for you in order to have an extension that blocks ads is another question.
As far as I know, the plan for Manifest V3 only included removing blocking from the WebRequest API and extensions using WebRequest could still see whatever activity they are given permission to view.
