Understand when Manifest V2 will stop working for extensions
Latest
October 9th 2024: an update on Manifest V2 phase-out.
Over the last few months, we have continued with the Manifest V2 phase-out. Currently the chrome://extensions page displays a warning banner for all users of Manifest V2 extensions. Additionally, we have started disabling Manifest V2 extensions on pre-stable channels.
We will now begin disabling installed extensions still using Manifest V2 in Chrome stable. This change will be slowly rolled out over the following weeks. Users will be directed to the Chrome Web Store, where they will be recommended Manifest V3 alternatives for their disabled extension. For a short time, users will still be able to turn their Manifest V2 extensions back on. Enterprises using the ExtensionManifestV2Availability policy will be exempt from any browser changes until June 2025. See our May 2024 blog for more context.
June 3rd 2024: the Manifest V2 phase-out begins.
Starting on June 3rd on the Chrome Beta, Dev and Canary channels, if users still have Manifest V2 extensions installed, some will start to see a warning banner when visiting their extension management page - chrome://extensions - informing them that some (Manifest V2) extensions they have installed will soon no longer be supported. At the same time, extensions with the Featured badge that are still using Manifest V2 will lose their badge.
Upcoming
June 2025: Chrome MV2 deprecation enterprise rollout
Enterprises using the ExtensionManifestV2Availability policy to ensure the continued functioning of Manifest V2 extensions in their organization will have one additional year - until June 2025 - to migrate the Manifest V2 extensions in their organization. Browsers with the policy enabled won't be impacted by the rollout of the deprecation until that time.
