Chrome Manifest V3 killed full ad-blocking, uBlock Origin gone for millions

Google forced Manifest V3 replacing the WebRequest API with declarativeNetRequest, making dynamic ad-blocking impossible. uBlock Origin is now disabled for all Chrome users as of mid-2026. Builders are porting to Firefox or shipping weaker MV3-native alternatives.

Gap Assessment

UnderservedExisting solutions leave gaps

Firefox and Brave keep MV2 alive; 2-3 MV3-native alternatives exist but all weaker than uBlock. Gap for a local-proxy extension restoring dynamic filtering on Chrome.
