Starting as early as June 1st for Manifest Version 2 deprecation

[Rick2025]

My question is will any of you be allowing  under User and Broswer settings> Apps and extensions

The Manifest V2 extension availability to extend a year. 

I know Hapara Highlights you would have to do this. Only issue is that once enabled any extension could use V2.

Have you ran in the admin panel  Chrome>Reports>Apps and extension usage- report to see what is using only V2?

https://developer.chrome.com/docs/extensions/develop/migrate/mv2-deprecation-timeline#:~:text=Users ...

In the admin panelyou under users and broswers > apps and extensions you can allow Manifest V2 an extension of time. One year I think it is. Problem is all V2 are allowed. If not enabled then it appears that products like ad blockers might stop working. Here is that discussion - https://www.reddit.com/r/chrome/comments/11peeuw/manifest_v3_discussion_and_impact_on_adblockers/

Love to hear the community thoughts

GoGuardian is requiring that we allow V2 as well. They say they are working on updating their extensions to support V3.

Happy 6/1(edit: two days early)!
Do we know of any other affected extensions?

[Rick2025]

You can download the list from in the admin panel.  Go Devices>Chrome>Reports> Apps and Extension Usage

It is interesting because things like sheets, docs, slides and many others are using Manifest versions 2

i've already allowed it for Securly, and uBlock Origin.

[Rick2025]

I didn't think you can allow it just for specific applications. I thought once you select it it will allow all manifest v2 apps to work. I think the only way to alow it would be to manage the store with only admin allowing the allow list to install. Is that what you are doing?

[Kim_Nilsson]

I think I meant I set it to Enable force-installed manifest V2 extensions, but now when I check it, it says Enable manifest V2 extensions. So allowing all V2. Maybe I changed it, because I was unsure whether anything else we have is available as V3 yet.

Thanks yet again for this group! I just got notifications that extensions/apps were blocked by an administrator and I wasn't anywhere near doing that and nothing showed in the audit log. It must be because of this. I get updates from Google all the time via the blog; why is it what I look back at my email, I have ZERO notification that this was happening. Is there another listserv on which I need to be?

***update*** My user account was moved into an OU that didn't have certain apps/extensions due to a user automation project.  BUT I'm glad to know this info anyway cause ublock and some other important ones are on the chopping block. Where are the vendors with updated versions? Also, I have a number of apps/extensions that have "not reported" under manifest versions or it's just blank. Is that normal/problematic?

The announcement from Google came out in 2019 but due to all the controversary, they delayed it for quite some time. There is a blog post in Chrome for Developers that had more details for extension developers concerning the migration. https://developer.chrome.com/blog/resuming-the-transition-to-mv3

I have GAC set to enable Manifest V2 extension at the root level because of GoGuardian. I am unsure when they will update to V3. Note that GoGuardian extension has an issue with non-managed devices and said, "Google has identified unexpected behavior on Chrome version 123 that disables self-hosted extensions (like GoGuardian) when a user's managed Google account is signed in to a non-managed or personal Windows device or Mac. The current workaround provided for this is to update to Chrome version 124, or roll back to Chrome version to 122."

Per our friends at CDW, this goes into affect with Chrome version 127:
