Raymond Hill, the creator of the popular content blocker uBlock Origin, has published the experimental extension uBO Minus for Chromium-based browsers.
The experimental extension uBOMinus is compatible with Manifest V3. The minus indicates that it is not as powerful as uBlock Origin. Hill reveals that uBO Minus uses the declarativeNetRequest API exclusively, which Google introduced in Manifest V3 to replace more powerful APIs of Manifest V3.
The extension does not require any extra permissions, including the "read and change all your data on all websites" permission. The consequence of this is that certain features are not supported by it. Hill lists cosmetic filtering, scriplet injections, CSP, redirect and removeparam filters specifically.
The Chrome extension uBO Minus uses the same default filter set as uBlock Origin, but in optimized form to take into account the limitations of Manifest V3.
Chrome users who want to give uBO Minus a try may download and install it
from the Chrome Web Store. New versions of uBO Minus will be released alongside the regular uBlock Origin extension for Chromium-based browsers and Firefox.
The extension has a simple interface, which highlights the number of blocked items only.
