About this extension

uBlock Origin is not an "ad blocker", it's a wide-spectrum content blocker with CPU and memory efficiency as a primary feature.

***

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

- EasyList (ads)
- Peter Lowe’s Ad server list (ads and tracking)
- EasyPrivacy (tracking)
- Malware domains

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

- Fanboy’s Enhanced Tracking List
- Dan Pollock’s hosts file
- MVPS HOSTS
- Spam404
- 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.

Free.
Open source with public license (GPLv3)
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.

Release notes for 1.31.0

See release notes.

New:

Click-to-load

Support to replace embedded frames with a click-to-load widget. Examples of usage:

||youtube.com/embed/$3p,frame,redirect=click2load.html
||scribd.com/embeds/$3p,frame,redirect=click2load.html
||player.vimeo.com/video/$3p,frame,redirect=click2load.html

Users of medium mode can experiment with a redirect rule to reveal embedded frames in a page:

*$3p,frame,redirect-rule=click2load.html

Or if you want to have click-to-load only for embedded widgets from specific origins being blocked (reminder: redirect-rule does not create a block filter):

||youtube.com/embed/$3p,frame,redirect-rule=click2load.html

Changes:

Resources redirected to local, neutered versions will no longer be collapsed as would occur if those resources were only blocked. This change is to enable implementation of the new click-to-load feature.

Cloud storage compression is now enabled by default.
