uBlock Origin Lite Chrome extension

uBlock Origin Lite blocks ads, trackers, and miners the moment you install it, using Chrome's built-in declarative filtering instead of a persistent background script. It's best for anyone who wants a lightweight, low-permission blocker. The catch: it's less customizable than the original uBlock Origin.

What uBlock Origin Lite does

uBlock Origin Lite blocks ads, trackers, and cryptominers as soon as it's installed, using Chrome's declarative net request system rather than constantly running JavaScript in the background. It ships with EasyList, EasyPrivacy, and Peter Lowe's tracking list enabled by default, and you can turn on more filter lists from the options page.

uBlock Origin Lite vs uBlock Origin

uBlock Origin Lite is the Manifest V3 version built to keep working as Chrome phases out older extension APIs. It trades some of classic uBlock Origin's dynamic filtering and element-picker depth for lower resource use and a design Chrome favors going forward. If you want maximum customization, the original uBlock Origin (where still available) offers more control.

Is uBlock Origin Lite safe?

The extension needs to inspect and block network requests to filter ads and trackers, which is normal for any content blocker. It's maintained by the same developer as the original uBlock Origin, and its privacy policy states it doesn't collect or sell user data.
