Key Facts

• Google Chrome's next update, specifically Chrome 150, set to be released later this month, will mark the end of popular ad blockers such as uBlock Origin due to the move to Manifest V3 for extensions.
• The move to Manifest V3 has been in the works for years and has been criticized by users because it would break most ad blockers due to the new permissions structure and Google's focus on privacy.
• A Chromium commit has removed support for the "kExtensionManifestV2Disabled" flag, referred to as "dead code," which was a loophole allowing some Manifest V2-based ad blocker extensions to still be used.
• A Google employee explained that MV2 extensions are no longer allowed in any supported version of Chrome, and they are removing support for them due to complexity, tech debt, and security risks.
