What uBlock Origin Lite is

uBO Lite applies filter lists declaratively under Chrome's Manifest V3, so in its default mode it blocks without reading page content. It exists because Chrome ended Manifest V2 support, which retired the original uBlock Origin there; the Lite rewrite trades configurability for that permission-light model.

Feature coverage

  • Declarative filter-list blocking
  • Optional per-site filtering modes
  • No broad read permissions in the default mode
  • Curated filter list selection
  • Open-source codebase

What stands out

  • Permission-light default is rare among content blockers
  • Listing discloses no data collection
  • Sixteen-million-user base with very active updates

Tradeoffs to know

  • Less configurable than the retired MV2 uBlock Origin
  • Manifest V3 rule limits constrain filter behavior
  • Stronger per-site modes do require page access

Is uBlock Origin Lite safe to use?

uBlock Origin Lite is among the safest extensions we cover: in default mode it filters without reading page content, the listing carries a declared no-collection disclosure, the code is open source, and 16,000,000 users run it. Granting the optional per-site modes increases blocking power and page access together — that choice stays yours.

Page access Minimal

Does its job without reading page content by default. The least to trust, and the easiest kind of extension to say yes to.

In its default mode it does not request broad page access; granting per-site optimal or complete modes increases both blocking power and access.

Store-disclosed data

The listing carries the developer’s declaration that it will not collect or use your data.

The Chrome Web Store listing says the developer has disclosed that it will not collect or use your data.

Does uBlock Origin Lite collect my data?

The Chrome listing carries the developer's declaration that it will not collect or use your data, and the default mode does not read page content at all — the disclosure and the permission model agree with each other.

Why does it sometimes ask for more access?

Its optional optimal and complete modes need per-site page access to block more aggressively. The extension works without them; granting them is a per-site tradeoff between blocking power and access.
