How's the adblocking in Vivaldi nowadays? I know Mozilla was like we will support manifest 2 so ublock origin can work at its best and I stuck with firefox for that, so I'm curious what's that like on Vivaldi. I seem to recall they said at some point that they would support V2 as long as it was on chromium, so how's that been going you folks?
