uBlock Origin Lite

uBlock Origin Lite is a content blocker built on the Manifest V3 architecture. It blocks ads, trackers, and cryptocurrency miners immediately after installation without requiring any configuration. The extension operates using a declarative approach, meaning the browser itself handles the filtering of CSS and JavaScript injections, eliminating the need for a continuous background process. As a result, uBlock Origin Lite consumes no CPU or memory resources during normal browsing; its service worker is active only when you open the popup panel or access the settings page.

Key Features

• Comes pre-configured with a default ruleset that mirrors uBlock Origin's standard filters, including built-in lists, EasyList, EasyPrivacy, and Peter Lowe's Ad and tracking server list. This ensures effective blocking out of the box.
• Additional rulesets can be enabled via the options page, accessed by clicking the cog icon in the popup panel. This allows users to customize filtering to their needs, such as adding regional or specific filter lists.
• The declarative filtering mechanism ensures that content blocking is performed reliably by the browser itself, reducing the extension's footprint and improving page load performance. This is particularly useful for users concerned about browser resource usage or those running multiple extensions.

By relying on the browser's native declarativeNetRequest API, uBlock Origin Lite provides a lightweight and efficient way to control unwanted content without sacrificing performance or privacy. It is ideal for users who want a set-and-forget solution that works silently in the background.
