@l33t4opera ah, thank you, I think it would be cause less of these kind of posts, when a moderator could make that one a sticky on this forum 😉
And jip, you are right regarding security. I don't use the chrome lib, because I now got used to the fact, that some videos just don't play back in Opera.
And one advantage for me also is, that those autoplay videos on some website don't play anymore in the background, those are sometimes annoying 😉
So I made peace with this function.
Also, when I want to watch a video which opera doesn't want to play, then I switch eiter to Firefox or mpv-player.
