I did receive a follow-up yesterday:

Hello,

I'll request to remove the post or at least correct it. This is informational mistake.

"Starting in June, the branch for Chrome 139 will begin, in which support for Manifest V2 extensions will be removed from Chrome. Unlike the previous changes to disable Manifest V2 extensions which gradually rolled out to users, this change will impact all users on Chrome 139 at once. As a result, Chrome 138 is the final version of Chrome to support Manifest V2 extensions"

We as Opera probably will sync an 139 intake in August/September 2025.

Sorry for the confusion.

I did receive the following message when I updated my manifest v2 extension early this month:

I asked for a timeline but didn't get an answer. So I updated it to v3 just to be safe.

@mazur90: It took a while for me to find your feedback. For some reason I don't get notifications from Opera.
But does it still not work in version 2.36.32? And are you sure that the extension is enabled in the menu and the ambient light effect is showing?

@dravenstorm Are you referring to the YouTube comments? You should be able to see them. If not, can you post a screenshot or video of what is going wrong?
