Chrome 150 will delete the ExtensionManifestV2Disabled flag, and Chrome 151 will remove remaining related flags, effectively ending support for the old extension framework. A limited DevTools method will remain but is impractical for daily use.","whyItMatters":"The removal of the last workaround means users who rely on advanced ad-blocking features on Chrome will have to switch to Manifest V3-compatible alternatives or change browsers.","webCardHtml":"\u003cp\u003eGoogle is closing the final loophole for Manifest V2 ad blockers in Chrome. The ExtensionManifestV2Disabled flag, which let users keep running extensions like uBlock Origin after the July 2025 cutoff, will be removed in Chrome 150. Chrome 151 will then strip out the remaining legacy flags: ExtensionManifestV2Unsupported, ExtensionManifestV2Availability, and AllowLegacyMV2Extensions. Google engineer Devlin Cronin cited complexity, technical debt, and security risks as reasons for dropping Manifest V2 support. A DevTools-based workaround will survive but requires manual page-by-page element editing, making it unusable for routine blocking.\u003c/p\u003e","blueskyPost":"Chrome 150 kills the last flag that kept Manifest V2 ad blockers working.
