I cannot remember the last time I saw a video in my facebook feed (in the feed, not directly linked). Maybe your facebook friends were just particularly annoying.

You are exceptionally lucky then. As of several years ago, they autoplay in my and everyone I've seen using facebook's feed all the time, many (perhaps even most for some) of them are ads rather than friend posted content. Fortunately they appear to stay muted until selected, but it's still annoying none the less. This is both via the website and in app (iOS, I'm sure other platforms suffer the same).

There's an option to disable autoplay in the settings.

This setting is not available in my Facebook video settings.

Firefox has an option to disable autoplay everywhere.

Thanks for this, I was unaware, I suspect I am not alone!
