uBlock Origin Lite
An efficient content blocker
Free
uBO Lite (uBOL) is a reliable and efficient 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 enable 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.
• Rewrite certain main_frame + regexFilter rules (to fix undue strict-blocking of certain web pages)
• Updated filter lists
