If I recall correctly, Vivaldi has this feature built-in, though as part of the ad-blocking feature (the "Cookie" list is classified as "Ads", not "Trackers"). Vivaldi's list defaults to IDCAC and EasyList Cookie, though, so we'll have to see whether Vivaldi will continue to use IDCAC list or switch to other solution.
