Partner center will stop accepting new MV2 extensions from 11th July




Hello, Edge Add-ons developers!


In May 2022, Microsoft announced the timelines for embracing Manifest Version 3 (MV3) for Microsoft Edge extensions and phasing out support for Manifest Version 2 (MV2).


As we move forward in this direction, the following change will come into effect starting 11th July 2022


All new extensions must use MV3 to be published to the Microsoft Edge Add-ons store.


You can continue updating your existing MV2 extensions that are already published on the Microsoft Edge Add-ons website.


This timeline is subject to change; for the latest updates, visit:


If you have any technical questions on your MV3 migration or the Microsoft Edge Add-ons ecosystem in general, you can reach out to us via our discussion forum on GitHub.


If you are facing any issues on Partner Center, or the Microsoft Edge Add-ons site; or you have any suggestions for us to improve the Microsoft Edge Add-ons ecosystem; you can submit those via our GitHub developer community.

@sonakshimore Edge will be dead to me once this goes down.  Sad.
