I was annoyed when I got the popup, so I stopped using vanilla yt and started using invidious or freetube. Since then ubo updated a couple times. I used vanilla yt the past couple days for hours of educational vids, and got no antiadblock messages. It wasnβt until I saw this post that I realized that ubo autofixed itself. Ask your father to reinstall ubo on ff and see if it fixes it. Also, I donβt ever log on to yt, so maybe that plays a factor.
