uBlock Origin

Finally, an efficient blocker. Easy on CPU and memory.

What is uBlock Origin?

uBlock Origin is a Chrome extension primarily designed for blocking unwanted content. It's not just an ad blocker, but offers a wide spectrum of actions, including ads and tracking, malware blocking, cookie warnings, and more, while being light on CPU and memory. It provides user flexibility in blocking content, enabling you to select the filters and create your own rules. All of this, for free and with transparency, as it’s an open-source project.
