Microsoft Edge Add-ons store warns Manifest V2 extensions may be removed soon

Microsoft is displaying warnings on Edge Add-ons store for Manifest V2 extensions that no longer meet its standards and may be removed soon. The warning appears on affected listings, including uBlock Origin, as Microsoft moves ahead with its transition from Manifest V2 to Manifest V3.

We recently reported that Microsoft Edge Canary had started showing deprecation warnings for installed Manifest V2 extensions. Now, the same warning is appearing on the Edge Add-ons store.

Edge Add-ons store displays the warning

The warning appears directly on affected extensions’ store listings, above the “Similar extensions” section. It reads: “This extension no longer meets Microsoft Edge standards and may be removed soon.” The message also includes a “Learn more” link to Microsoft’s explanation of the Manifest V3 transition.

This wording differs from the earlier message shown for installed extensions, which said: “This extension was disabled as it is no longer supported in Microsoft Edge.” The new warning instead says the extension no longer meets Microsoft Edge standards and may be removed soon.

We also confirmed that warnings for installed extensions appear in Edge Beta, Dev, and Canary, but not in the Stable release. In our screenshot, uBlock Origin remains enabled in Edge Canary despite the warning, so the message does not necessarily mean an extension has already been disabled.

Why is Microsoft warning users?

Microsoft is phasing out Manifest V2 in favor of Manifest V3, affecting extensions that have yet to move to the newer platform. The warnings are part of that transition and do not necessarily mean the affected extensions are malicious or unsafe.

Microsoft had already outlined plans to show deprecation warnings on both Edge’s extension management page and the Edge Add-ons website. The store warning gives users another place to see that an extension may be removed, even before they open the browser’s extension settings.

Users who rely on affected extensions may need to check whether their developers offer compatible versions or consider alternatives. The warning itself does not confirm that an extension has already been removed.
