Google to Phase Out Chrome's Manifest V2, Impacting Ad Blockers

Starting June 3, Chrome will begin disabling V2 extensions, pushing users towards the more restrictive Manifest V3.

Manifest V3 aims to improve security, privacy, and performance but restricts ad-blocking capabilities.
Beta, Dev, and Canary versions of Chrome will display warnings about the impending change.
Over 85% of actively maintained extensions have transitioned to Manifest V3, including popular ad blockers.
Enterprise users can delay the transition to Manifest V3 until June 2025.
Firefox will continue to support Manifest V2 while adopting beneficial aspects of V3.
