An efficient blocker: Fast, potent and lean, 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

Risk impact

uBlock Origin requires a lot of risky permissions and is not safe to use. Avoid installing this add-on unless you absolutely trust this publisher.

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypass your security settings, and access your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Risk likelihood

uBlock Origin has earned a good reputation and can be trusted.

Risk likelihood measures the probability that an Edge add-on may turn malicious. This is determined by the publisher and the Edge add-on reputation on Edge Add-on Store, the amount of time the Edge add-on has been around, and other signals about the Edge add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing an Edge add-on, especially ones with higher risk impact and/or higher risk likelihood.

Szerintem nem is interneteznék, ha nem lenne ez a bővítmény. Az AdBlock ehhez képes semmi.

We paid for an OS and apps. Businesses have no right to, additionally, subject us to unsolicited junk mail and advertising on our PCs. Thank you (all involved) for uBlock - a fast, effective and invisible solution.
