Understand when Manifest V2 will stop working for extensions
Latest
June 3 2024: the Manifest V2 phase-out begins.
Starting on June 3 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.
This will be followed gradually in the coming months by the disabling of those extensions. 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 after the extensions are disabled, users will still be able to turn their Manifest V2 extensions back on, but over time, this toggle will go away as well.
Like any big launches, all these changes will begin in pre-stable channel builds of Chrome first – Chrome Beta, Dev, and Canary. The changes will be rolled out over the coming months to Chrome Stable, with the goal of completing the transition by the beginning of next year. Enterprises using the ExtensionManifestV2Availability policy will be exempt from any browser changes until June 2025.
