If you have uBlock Origin, you might notice Chrome automatically disabling the extension.

Google Chrome has begun to phase out uBlock Origin. The developer of the free ad blocker, Raymond Hill, recently reposted a screenshot that shows Chrome automatically turning off uBlock Origin because it is “no longer supported.”

The change comes as Google Chrome migrates to Manifest V3, a new extension specification that could impact the effectiveness of some ad blockers. uBlock Origin has launched uBlock Origin Lite, which uses Manifest V3, in response to the transition. However, you have to manually install the extension because it’s “too different from uBO to be an automatic replacement,” according to a FAQ Hill that posted to GitHub.
