Description
uBO Lite (uBOL), an experimental permission-less MV3 API-based content blocker.
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/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/modify data" permissions at install time.
To grant extended permissions on a given site, open the popup panel and click the Sun icon:
The browser will then warn you about the effects of granting the additional permissions requested by the extension on the current site, and you will have to tell the browser whether you accept or decline the request:
If you accept uBOL's request for additional permissions on the current site, it will be able to better filter content for the current site:
When the Sun icon is blue, this means you explicitly granted extended permissions on the current site. The badge number beside the Sun icon represents the number of distinct CSS/JS resources which can/will be injected on the current site, leading to better content filtering on that site.
You can revoke formerly granted extended permissions by simply clicking the Sun icon again. You can view/manage all the sites for which you granted extended permissions by clicking the "Details" button of uBOL's card in your browser's extensions page.
However, [...]
uBOL allows you to explicitly grant extended permissions on specific sites of your choice so that it can better filter on those sites using declarative cosmetic and scriptlet injections.
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.
Keep in mind this is still a work in progress, with these end goals:
- No broad host permissions at install time -- extended permissions are granted explicitly by the user on a per-site basis.
- Entirely declarative for reliability and CPU/memory efficiency.
Release notes
- Renamed "uBO Lite" from "uBO Minus"
- Added ability to enable/disable filter lists
- Added support for i18n
- Added support for optional permissions through new button in popup panel. Consequences:
- Support for specific plain CSS-based cosmetic filtering
- Support for scriptlet-based filtering (json-prune, set-constant, abort-current-script)
- Fixed dark theme issue
- Improved reliability of cosmetic filtering
