They are one of the most infuriating things for me. But I curious to know why is this a popular pattern in websites. Do people actually stop whatever they were planning to do and watch the video ?
I’ve blocked them on all my devices. But once in a while I see them when I use someone else’s devices and I wonder.
Right click on the video under ublock select block element. A popup will show up in the bottom right where you can fine tune. If the video has a custom right click menu just do it anywhere else and in the fine tune options click select element then the video. Also make sure you use uBlock Origin.
