No. The Autoplay chrome flag was added but then removed/scrapped sometime in early 2019. You can only stop autoplay videos by using extensions now. The only extension that is actively maintained (and actually works) is called "AutoplayStopper" https://chrome.google.com/webstore/detail/autoplaystopper/ej...

There's no flag; it's on by default. Do you have a link to an article talking about the autoplay policy being reverted?

No, I am speaking by my own use of Chrome only. Go to YouTube or any large news site, and the videos still autoplay, regardless of whatever chrome settings/flags are now supposedly default.

That's not actually what's going on. You can find an explanation here: https://developers.google.com/web/updates/2018/11/web-audio-...

No, but I can confirm that in FF69 it's finally blocking those banal CNN videos that seem to accompany every. single. article.

They've switched to checking an "mei" score to see if a video is allowed to autoplay on a site:

It is blocked only if the video has sound. Muted videos can be played automatically.
