Chrome does not have any way to stop video auto play?

Firefox blocks auto playing videos with sound by default. And you can also configure it to block all autoplay or or allow it globally, or per-website. https://support.mozilla.org/en-US/kb/block-autoplay

Chrome is not there to serve you. It is to serve Google.

There's no reason to use Chrome today. Maybe there was a reason to use it many many years ago. With plenty of options today the sane choice is to select another browser. I run Firefox even on my phone. If for some reason I need a Chrome based browser, on my phone I switch to Brave, on the desktop to Chromium. But I rarely open any of those at all as Firefox has been doing extremely well.

Hmm, but there are ways of streaming video that don't have traditional Play/Pause/etc. buttons. If there's no way to turn it off, how can Chrome "learn my preferences"? Maybe it can sense me swearing? Not a Chrome user and definitely not starting now. Autoplay video is one of my great annoyances on the modern web.

AutoplayerStopper [1] is still available if you set the policy to enable manifest V2 extensions [2] which should still work for a few more months.

This is totally unsurprising. I'm sure Google realized that autoplaying gives them more ad revenue somehow. It was a massive mistake to allow an ad company control over your browser.

Quoting part of k1t's comment[0] for visibility:

"I do recall a Firefox discussion about how they can't 100% block videos because there will always be another way - eg do animated gifs count, or javascript that shows a rapid sequence of images [...]"

I also recall this being a justification given for auto-playing muted or audio-less video (i.e. because blocking "efficient" muted video playback will just lead to malicious actors using "less efficient" means of "image sequence" playback thus increasing the negative impact further).

On a related note, the other day I also discovered (while debugging why an audio demo didn't work the same way it did six years ago :D ) that there's now also a concept called "Sticky Activation" which can also impact "Autoplay of Media and Web Audio APIs (in particular for AudioContexts)"[1].

See: https://developer.chrome.com/blog/autoplay

tl;dr: The browser attempts to learn your preference for each site automatically based on how you interact with videos. You can see what it's calculated by visiting chrome://media-engagement

OK Chrome shall be gone/uninstalled/not-used from all my computers and shall recommend it be removed from all my friends computers with the explanation of their behavior and loss of trust and respect for us users!

If its youtube, change your settings, Its autoplay on default.

If its your website, just set it up like you want in the video tag.

Not sure why this post wasnt removed tho. This is just general issues you could have googled for a solution or askes a site dedicated to it such as stack overflow.

still seems to work for me?

I find this behavior quite annoying. I would like to be able to block auto play by default across the entire Internet. I have to imagine this is simply a way to allow Google’s ad networks to play annoying ads.

could you provide an example of a website that shows this behaviour?

I made a small ViolentMonkey script to stop autoplay on Youtube, which is really annoying

Use uBlock to remove that element. Dont know if it will save data.

Chrome is not for you. Chrome is for monetizing your attention.

Maybe they don’t want you to do that? YouTube has "autoplay next video" by default and you can’t disable that either. This is the kind of controlling behavior that I expect from Google.
