A Manifest V3 ad blocker that actually works

What Manifest V3 changed

Chrome's Manifest V3 replaced the old dynamic request-blocking API with a declarative one and set limits on how rules work. Blockers based on the old approach had to be rewritten, and some lost capability or were discontinued, which is why many longtime users noticed ads come back.

Why native Manifest V3 blockers stay strong

A blocker designed for Manifest V3 uses the declarative rule engine as Chrome now expects, combined with cosmetic filters in the content script and main-world scripting for advanced cases. AdOff was born Manifest V3-native: network rules, cosmetic hiding, video neutralization and Stealth all work inside the new model.

What to check before installing

Make sure the blocker explicitly supports Manifest V3 and is actively maintained. AdOff is native Manifest V3 on Chrome, Edge, Opera and Brave, plus Firefox (Safari coming soon).
