The reason Mozilla is implementing Manifest V3 is to maintain cross-browser support for extensions. There are many extensions that will work just fine and not having the new APIs on Firefox would mean just loosing them. And I’m not saying this as a Google supporter, I hate them, but we have to be objective. Also, Firefox devs are pushing forward security with better and better site isolation, cookie isolation and now with RLBox. And if they implement more stupid features like themes, it’s totally fine. People complain if Firefox has a low market share and then complain again when they implement user-friendly design things.
