An efficient, open-source ad blocker that removes ads and trackers with minimal impact on page load speed.
uBlock Origin is the ad blocker that security researchers recommend. It blocks ads, trackers, and coin miners using filter lists you can fine-tune, all while using a fraction of the memory of competing blockers. The default filters clean up the web dramatically — pages load faster, scroll smoother, and use less data. It has no acceptable-ads program, so nothing gets through unless you allow it. Open source and audited, it's the rare privacy tool that is also the best at its job, available for Chrome, Firefox, Edge, and Safari.
