Having trouble figuring out how to play StreamLegends once you’ve installed the extension? Don’t forget to activate it! You can do that by visiting your extensions dashboard and clicking the activate button below the StreamLegends extension on the lefthand side of the dashboard. Once activated, you’ll be able to play below the video on any Twitch channel on which the broadcaster has installed StreamLegends.
