Commercial web browsers including Brave, Opera, and Vivaldi won’t be disabling ad blocker extensions as desired by Google. These browsers are based on the the same open source codebase that is used with Google Chrome. Google maintains an open source project called Chromium as the base of its Chrome browsers.
According to ZDnet, “At the end of May, Google made a new announcement in which it said that the old technology that ad blockers were relying on would only be available for Chrome enterprise users, but not for regular users.”
Chromium has become standard for web browsers; except for Safari and Firefox, almost everyone is using Chromium--including Microsoft Edge. Chromium derivates Brave, Opera, and Vivaldi have said they will not follow Google into crippling ad-blocking.
