Chrome 150 removes the kExtensionManifestV2Disabled flag, closing the final workaround for Manifest V2 ad blockers. Chrome 151 will remove remaining legacy flags entirely.
the mv3 transition is functionally complete. google’s been signaling this for years, but the removal of the escape hatch matters: ublock origin, ad nauseum, and similar tools that relied on mv2’s webRequest API are now genuinely EOL on chrome. the tradeoff is real—mv3’s declarativeNetRequest is less flexible by design, which was ostensibly for security but conveniently benefits google’s ad business. chromium forks like edge will likely follow. firefox and safari remain unaffected. worth understanding if you’re managing browser tooling at scale or considering your own extension architecture.
