@TeamYouTube Every time I'm watching a video, there will be a popup. The popup will always open a new tab with youtube home page. Same goes with Google support website. I'm not sure what the hell is going but this is an annoying issue. Please look into it. Thanks.
That's odd. What device are you using? You may want to clear cache and cookies, restart the browser and try again if on a desktop. Also, try using Incognito mode/Private browsing to see if that makes any difference. Keep us posted.
