An experimental, permission-less content blocker. Blocks ads, trackers, miners, and more immediately upon installation.
uBO Lite (uBOL) is an experimental *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.
uBO Lite 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.
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.
To grant extended permissions on a given site, open the popup panel and pick a higher filtering mode such as Optimal or Complete.
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.
You can set the default filtering mode from uBOL's options page. If you pick the Optimal or Complete mode as the default one, you will need to grant uBOL the permission to modify and read data on all websites.
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.

want to say thanks for preparing for the inevitable. really appreciate being able to test this out to know the difference between MV2 and MV3 limitations. 1 that really bothered me is youtube ads. are these not going to be blockable in MV3? keep up the good work ! |

I am a big fan of uBlock. I am really happy to see it thrive even after Manifest v3. Really wish that MV3 constraints did not exist :( but it is what it is. Thank you so much for making such a beautiful extension. |

I am a big fan of this idea of a much simpler permissionless ad blocker. I honestly hope that this project remains as simple as it is. I spend a fair bit of time disabling extra functionality in uBlock Origin when I add it to a new machine. |

Gorhill, you've done it again. It works fine. I manage a regular uBO deployment in a large enterprise environment and its sad we will have to rely on a reduced functionality version, but if we are able to add "allow list" URLs like we could with MV2, then it would be fine for our use case. |

still the best and it is working well, I haven't tried with other sites but I can see it still blocks ads. Hoping to see, at least, the domain whitelist functionality. |
