chromium derivatives, such as vivaldi, brave, edge, etc... must have an open source fork on top chromium which removes any manifest v3 enforcement and ensures ad blocking capabilities. if they will have to do it alone, it would be too great of an effort as I'm sure google with couple v3 code everywhere and make it hard to remove this enforcement alone.

they also need to help remove blocking popups like youtubes one which works and act exactly like an ad.

I'm sure this could bring more usage to these browsers. I've moved to vivaldi and never looked back
