uBlock Origin Lite

A permission-less content blocker. Blocks ads, trackers, miners, and more immediately upon installation.
uBlock Origin Lite is a permission-less MV3-based content blocker designed for Firefox. Built on the same ruleset as uBlock Origin, it blocks ads, trackers, miners and other unwanted content. The add-on only becomes active when interacting with the popup panel or option pages, which minimizes CPU/memory usage. It doesn’t require broad permissions to run, but permissions can be explicitly granted on a per-site basis for a robust filtering experience.
