I use Firefox with ublock origin and didn't have any trouble with videos auto-playing.
Interesting. For me with Chrome+ublock origin I still get the auto-playing video. With Firefox+ublock origin the video appears but doesn't play. Instead it shows a red and white "I'm still loading" icon over the video, which is quite annoying but much better than auto-play. Is this what you get?
How long till ZDNet realises that autoplay model is egregious?
Why do they bother with autoplaying videos when browsers mute them?
