Chrome eliminates final Manifest V2 workarounds

Google's final execution of Manifest V2 marks a contentious milestone in web browser history, prioritizing developer control and API simplification while intentionally reducing the effectiveness of advanced ad blocking. The removal of the legacy support flags closes the final loophole, forcing users to either transition to less powerful Manifest V3 alternatives like uBlock Origin Lite or migrate to non-Chromium browsers like Firefox that maintain legacy support. As Chrome consolidates Manifest V3 as the dominant standard, other Chromium-based browsers like Edge and Opera are expected to follow suit. While Google frames the transition as necessary to eliminate security bugs and technical debt, it creates a significant opportunity for alternative browsers to capture privacy-conscious power users.
