In recent days, the way that CNN autoplays its videos has changed and old methods of blocking them no longer work. I suspect it has something to do with their using HTML5 instead of Flash. Any suggestion on how to block them now?

After further searching, I've found plug-ins for both Firefox and Chrome that handle both the Flash and HTML5 attempts to auto-play videos on CNN. It appears that CNN is now trying up to six times to auto-play a video, and these plug-ins catch them all! https://www.technologyhint.com/stop-video-autoplay-chrome-firefox/

  • I have Chrome 58, and installed both of those extensions. CNN videos still autoplay about 75% of the time. Jun 9, 2017 at 19:59
  • None of these work in Chrome anymore (Chrome 62). Aug 21, 2017 at 18:51
  • I've switched to FlashStopper, and have no problems. I have version 60.0.3112.101 of Chrome.

You can try this extension in Chrome:
Disable HTML5 Autoplay

  • This is no longer maintained, unfortunately. Autoplaying videos are the new pop-up windows, I really hope one of the browser vendors come up with a way to permanently disable them without requiring downloading and configuring an add-on.
