## What it is
uBO Lite is an efficient, permission-free content blocker browser extension built on the Manifest V3 API, from the uBlock Origin team. It operates entirely declaratively so the browser handles CSS/JS injection for filtering without a permanent background process consuming CPU or memory.

## Use cases
- block ads in chrome without an extension permission prompt
- lightweight ad blocker for firefox mv3
- block trackers and ads in edge and safari
- content blocker that uses no cpu or memory while filtering
- managed enterprise policy settings for browser ad blocking
- enable extra filter lists like easylist and easyprivacy

## When to choose
- you need an MV3-compatible ad blocker for Chrome, Edge, Firefox, or Safari
- you want efficient declarative filtering with minimal resource usage
- you need enterprise-managed content blocking policies

## When to avoid
- you need uBlock Origin's full dynamic filtering and advanced customization features
- you need a general-purpose security tool beyond ad and tracker blocking
