Google will remove the last traces of Manifest v2, the feature that enabled robust ad-blocking extensions like uBlock Origin, in Chrome versions 150 and 151. Chromium forks — Edge and Opera — have signaled they will follow Google’s lead, though no firm deadlines have been set. Manifest v3-compliant ad blockers work, albeit with limitations.

Firefox (and its derivatives) and Safari will continue to support Manifest v2.
