How we separated the picks

Chrome's move to Manifest V3 retired the original uBlock Origin there, and every pick here is a current MV3 extension. Blockers differ less in raw filter lists than in their defaults, how much page access they ask for, and how much control they hand you. We took default behavior and feature sets from each developer's documentation, and adoption, ratings, upkeep, and data disclosures from the live Chrome Web Store listings, checked October 12, 2026.

What to check before installing

  1. Run one blocker at a time: stacking two duplicates work and makes broken pages harder to diagnose.
  2. Check the defaults—AdBlock and Adblock Plus allow Acceptable Ads until you opt out of that list.
  3. Blocking needs wide reach, so prefer an open-source or long-established publisher and grant the narrowest mode that works.
  4. Keep a per-site pause handy for checkout, banking, and video pages that misbehave.
