Update your extensions from Manifest V2 to V3 #27
May 27, 2022 · 2 comments · 2 replies

Microsoft announced the decision to embrace Manifest V3 to help reduce web fragmentation for all developers and enhance privacy, security, and performance for end-users.

From 11 July 2022:

  • Microsoft Partner Center will no longer accept new Manifest V2 extensions with visibility set as Hidden or Public. Developers must use Manifest V3 to publish new extensions to the Microsoft Edge Add-ons website.
  • You may continue to update existing Manifest V2 extensions. For more details on the deprecation of Manifest V2 extensions, visit Overview and timelines for migrating to Manifest V3.

Migrating from Manifest V2 to V3 will bring several structural changes to how the browser handles extensions. Manifest V3 is an initiative of the Chromium project.

Here is the link to the official announcement made on Microsoft Edge Insider Tech community

How do you respond to concerns from the main uBlock Origin developer (uBlockOrigin/uBlock-issues#338 (comment))? This extension has over 10 mio users on MS Edge and won't work after V3 becomes mandatory.

I am also concerned about this. Very little has been told. If Edge doesn't support full functionality, in fact, privacy is compromised...


I'm too curious about how this will end.
Seeing their roadmap they will definetly drop v2 one day:

When this change is released, Microsoft Partner Center will not accept updates to existing Manifest V2 Microsoft Edge Add-ons. Microsoft Edge will no longer support or run Manifest V2 Microsoft Edge Add-ons.

Note that by using Microsoft Edge Enterprise Policies, Enterprise Accounts can allow Manifest V2 Microsoft Edge Add-ons to run and operate on Microsoft Edge.

I think microsoft have done a good job with edge till now, but if ublock will not work anymore I'll never use edge again and I don't think I'm the only one.

Will MS Edge also kill background service workers every 5 minutes like what Chrome does? Any way to configure the time range or disable it?
