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 Chrome extension that offers efficient, permission-less content blocking. Upon installation, it immediately stops ads, trackers, and miners without requiring excessive permissions. This MV3-based extension uses a default ruleset aligned with uBlock Origin's filter set. But unlike uBlock Origin and other blockers requiring broad permissions, uBOL only requires permissions for specific sites where you wish to enhance its filtering capabilities. It is primarily declarative, freeing up CPU/memory resources by letting the browser handle CSS/JS injection-based content filtering, and only requires engagement when you interact with its pop-up panel or option pages.

Summary
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.
