Google has removed all remaining Manifest V2 extensions from the Chrome Web Store, including uBlock Origin, as part of its transition to Manifest V3. This change affects not only Google Chrome but also other Chromium-based browsers that rely on the Chrome Web Store. The removal of Manifest V2 extensions means they can no longer be installed or updated from the Chrome Web Store, although existing installations will remain functional. Brave browser has decided to host some popular Manifest V2 extensions on its own backend.
