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 1.28.0

See release notes.

Changes:

##script:inject(...), which has been deprecated in favor of ##+js(...) for more than two years, is no longer supported.

It's no longer possible to point-and-click to create allow (green) rules from within the popup panel by default. This change is motivated by seeing way too many cases of improper usage of dynamic filtering in which users are creating allow (green) rules where noop (gray) rules should have been used. You can get back temporarily the ability to create allow rules from within the popup panel by tapping twice the Ctrl key.

Improved syntax highlighting of static filters in "My filters" and asset viewer. Additionally, in "My filters":

Ability to toggle commenting out of filter(s) by pressing the Tab key
Auto-completion using Ctrl-Space, this works for:
- Static filter options
- Resource names for redirect= option
- Procedural operators for cosmetic/HTML filters
- Scriptlet names for ##+js filters

Closed as fixed:
