From Ars Technica:
Google is taking on the irritating trend of auto-playing Web videos with its Chrome browser. Starting in Chrome 64, which is currently earmarked for a January 2018 release, auto-play will only be allowed when the video in question is muted or when a “user has indicated an interest in the media.”
The latter applies if the site has been added to the home screen on mobile or if the user has frequently played media on the site on desktop. Google also says auto-play will be allowed if the user has “tapped or clicked somewhere on the site during the browsing session.”
. . . .
In addition, Google is adding a new site muting option to Chrome 63 (due for release in October), which allows users to completely disable audio for individual sites. The site muting option will persist between browsing sessions, allowing for some degree of user customisation.
However, Apple’s upcoming Safari 11 browser—which features its own auto-play blocking tools—will allow for more granular control, enabling users to mute auto-playing media with sound or block auto-playing media entirely on specific sites or on the Internet as a whole.
. . . .
In addition to auto-play blocking, Google is planning to implement ad-blocking inside the Chrome browser. The Google ad-blocker will block all advertising on sites that have a certain number of “unacceptable ads.” That includes ads that have pop-ups, auto-playing video, and “prestitial” count-down ads that delay content being displayed.
