CHANGELOG: https://github.com/gorhill/uBlock/releases


An efficient blocker: easy on memory and CPU footprint, and yet can load and enforce thousands more filters than other popular blockers out there.

Illustrated overview of its efficiency: https://github.com/gorhill/uBlock/wiki/uBlock-vs.-ABP:-efficiency-compared

Usage: The big power button in the popup is to permanently disable/enable uBlock Origin for the current web site. It applies to the current web site only, it is not a global power button.


Flexible, it's more than an "ad blocker": it can also read and create filters from hosts files.

Out of the box, these lists of filters are loaded and enforced:

- EasyList
- Peter Lowe’s Ad server list
- EasyPrivacy
- Malware domains

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

- Fanboy’s Enhanced Tracking List
- Dan Pollock’s hosts file
- hpHosts’s Ad and tracking servers
- Spam404
- And many others

Of course, the more filters enabled, the higher the memory footprint. Yet, even after adding Fanboy's two extra lists, hpHosts’s Ad and tracking servers, uBlock Origin still has a lower memory footprint than other very popular blockers out there.

Also, be aware that selecting some of these extra lists may lead to higher likelihood of web site breakage -- especially those lists which are normally used as hosts file.

For users by users.

If ever you really do want to contribute something, think about the people working hard to maintain the filter lists you are using, which were made available to use by all for free.

  • Been using it for years, never had an issue with it. It blocks a lot of unwanted ads and malware.

  • I think uBlock is a good adBlock, but it blocks some important images and websites...
