uBlock Origin: The Best Free Ad Blocker
uBlock Origin is a free, open-source, wide-spectrum content blocker for Chrome, Firefox and Edge. Honest review and setup notes.
What it is
uBlock Origin is a free and open-source browser extension that blocks ads, trackers and malware domains using community-maintained filter lists. It is CPU- and memory-efficient and does not sell user data.
Unlike many 'free' ad blockers, uBlock Origin has no acceptable-ads program and no paid whitelist -- it is funded by donations and run by volunteers under a GPLv3 licence.
What you get for free
100% free and open-source, forever. No paid tier, no account, no upsell.
Who it is for
Anyone who uses a web browser. It is the single highest-impact privacy install most people can make.
Our take
Our #1 pick with no caveats. We do not earn a cent recommending it and we recommend it first anyway -- that is the whole point of this list.
