uBlock Origin (uBO) is not an "ad blocker". It is a wide-spectrum content blocker with CPU and memory efficiency as primary features.


Out of the box, uBO blocks ads, trackers, coin miners, popups, etc. through the following lists of filters, enabled by default:

  • EasyList (ads)
  • EasyPrivacy (tracking)
  • Peter Lowes Ad server list (ads and tracking)
  • Online Malicious URL Blocklist
  • uBO's lists

More lists are available for you to select if you wish:

  • EasyList Cookie
  • Fanboy Annoyances
  • AdGuard Annoyances
  • Dan Pollocks hosts file
  • And many others

Additionally, you can point-and-click to block JavaScript locally or globally, create your own global or local rules to override entries from filter lists and many more advanced features.
