fantastic. Also, just so you don’t have all that “YoU hAvE tHrEe ViDeOs LeFt” BS copy paste this to the “my filters” tab (go to about:addons, click on uBlock, there dots, “preferences”, then “my filters”) and you should be good to go:

youtube.com##+js(set, yt.config_.openPopupConfig.supportedPopups.adBlockMessageViewModel, false)

youtube.com##+js(set, Object.prototype.adBlocksFound, 0)

youtube.com##+js(set, ytplayer.config.args.raw_player_response.adPlacements, [])

youtube.com##+js(set, Object.prototype.hasAllowedInstreamAd, true)

Also here is another that blocks shorts entirely:
