What happened
Google removed all remaining Manifest V2 extensions from the Chrome Web Store on September 1, 2026, including uBlock Origin. MV2 extensions already installed on Chrome 138 or earlier stay functional but cannot receive updates or be reinstalled. Brave is independently hosting four popular MV2 extensions—AdGuard, uBlock Origin, uMatrix, and NoScript—on its own backend.
Why it matters
If you ship a Chrome extension, you must have already migrated to MV3 or your users can no longer install or update it from the Chrome Web Store. If you rely on uBlock Origin or other MV2 content blockers, switch to Brave or find an MV3-compatible alternative like uBlock Origin Lite, since the original UBO is no longer installable or updatable through CWS on any Chromium browser.
Discussion angle
What MV3's webRequest limitations mean for content blockers and whether Brave's independent hosting of MV2 extensions signals a meaningful fragmentation of the Chromium extension ecosystem.
