Google Chrome Disables UBlock Origin

The market impact is negative for ad-blocking software providers like UBlock Origin, as Alphabet Inc.'s Manifest V3 update restricts their functionality on Google Chrome and other Chromium-based browsers. This could lead to a shift in browser market share towards Firefox, which continues to support older extensions, and potentially benefit advertisers.
Alphabet Inc. is implementing its new Manifest V3 extension framework for Google Chrome, which has led to the automatic disabling of older extensions, most notably the popular ad blocker UBlock Origin. While Alphabet Inc. claims the update improves privacy and security, critics argue it benefits advertisers by limiting ad-blocking capabilities. Users are reporting notifications that their extensions are 'no longer supported' and are given options to remove or manage them. This change also affects other Chromium-based browsers like Microsoft and Brave, which will offer limited or no support for Manifest V2 extensions. In contrast, Firefox has stated it will continue to support Manifest V2, positioning itself as an alternative for users who wish to retain full ad-blocking functionality.
