uBlock Origin

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 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
- MVPS HOSTS
- 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 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.

***

Without the preset lists of filters, this extension is nothing. So 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.

The latest version enabled an extra sidebar that I can't disable, please fix. This happened maybe 2 hours ago at most, I've been using uBlock for half a year now without issue.

best extension for privacy and security. This is just one part of a layer approach that will help a user create a more trustworthy and more secure online experience.

I use this ext on Yandex Browser. I also use the following extensions:

adguard
privacy badger

when tested against well known browser security sniffers, I find my online experience is very well secured.

recommended!

now, if yandex would offer a free unlimited VPN (similar to Opera builtin vpn), I would be very pleased.

I use this ext and yandex combination to browse "socially". I do not use it for banking, or any online financial transactions. For simple news reading and social browsing, it is suitable. But only for that.

sdo-epic's concerns about the permissions while well meaning should not determine whether or not you install this. Look at the perms of Privacy Badger - they are the same! Look at other ad blockers, they are mostly the same. Use this based on features not fear!
