uBlock Origin Lite

uBlock Origin Lite

A permission-less content blocker. Blocks ads, trackers, miners, and more immediately upon installation.

What is uBlock Origin Lite?
uBlock Origin Lite is a MV3-based Edge add-on that offers permission-less content blocking. Its default ruleset mirrors uBlock Origin's filterset, ensuring immediate ad, tracker, and miner blocking upon installation. It operates declaratively, meaning it does not consume CPU/memory resources unless you interact with it, enhancing browser efficiency. By choice, users can offer uBOL additional permissions for optimal performance on specific sites, maintaining user control and flexibility.

Summary
Analyze keywords

uBO Lite (uBOL) is a permission-less MV3-based content blocker.

The default ruleset corresponds to uBlock Origin's default filterset:

  • uBlock Origin's built-in filter lists
  • EasyList
  • EasyPrivacy
  • Peter Lowe’s Ad and tracking server list

You can add more rulesets by visiting the options page -- click the Cogs icon in the popup panel.

uBOL is entirely declarative, meaning there is no need for a permanent uBOL process for the filtering to occur, and CSS/JS injection-based content filtering is performed reliably by the browser itself rather than by the extension. This means that uBOL itself does not consume CPU/memory resources while content blocking is ongoing -- uBOL's service worker process is required only when you interact with the popup panel or the option pages.

uBOL does not require broad "read and modify data" permission at install time, hence its limited capabilities out of the box compared to uBlock Origin or other content blockers requiring broad "read and modify data" permissions at install time.

Funktioniert sehr gut, für die Zukunft vermutlich mein Standard-AD-Blocker, gute Arbeit!

Excellent extension for the new Manifest V3 API. I don't use the internet without uBO Lite, now.
