Good. I know a news website that was on purpose disabling sound on videos to prevent that. So not only does it autoplay, you need to click to unmute anyway to actually hear it!
Why do news websites want to shove autoplaying videos on people's throats so much, what's wrong with playing at any time when you want?
And why do news websites even care about doing shoving it to the small percentage of people who actually bother to disable autoplay in their browser?
P.S. I already had autoplay for videos without sound disabled through about:config flags, but some videos managed to autoplay anyway. I wonder if they also fixed that issue, or simply made the about:config flag part of the settings dialog.
