For me, a browser has to support uBlock Origin, as it works today. I don't want the browser vendor deciding how ads and trackers get blocked, it's a conflict of interest and it's never been done better than uBO anyway. Won't all chromium based browser break proper ad/tracker blocking once that manifest v3 thing happens?
Brave said they wouldn't. Who knows. I switched and I'm liking it a lot thus far, but if they implement manifest v3, all that will remain of me will be a puff of smoke
