Manifest v3 is the new cookie replacement in Chrome right? Is Firefox also adopting it? I think Google's version helps them monopolize information collection and inhibit add blocking, I hope Firefox's version doesn't do that? What's the benefit?
Manifest V3 changes capabilities and meta-data about extensions, including limiting lots of things that worsen the experience for AdBlock Users.
Google's "cookie replacement" is Ad Topics, which collects your browser history and puts it into categories, sending those categories to websites.
That is the Chrome implementation; Firefox doesn't and won't impose those limits.
As per the MV3 Specification, it is supposed to remove some APIs.
Firefox included them anyways cuz they're not assholes.
I think there's multiple specifications at this point. There's Chrome describing what they're doing unilaterally, and then there's the WebExtension working group that's trying to get alignment among several browsers.
