Prevent Firefox browser from autoplaying YouTube HTML5 videos. Thanks to click-to-play, which blocks flash videos from autoplaying in Firefox and Chrome browsers, now we need to find a solution for HTML5 videos as well.
Have you annoyed with certain (HTML5) videos being automatically played in websites like YouTube or Facebook news feed, you can stop that from happening in Firefox browser natively through a preference.
Stop HTML5 videos from auto-playing in Firefox
1. Visit about:config,
2. Find the preference media.autoplay.enabled using search and toggle its value to False.
Note: Let me tell you this setting will be honored only in Firefox 41 or later versions, but not in the current Firefox 38. You can install Flash Control or No Script add-ons to achieve the same in stable or any other version of Firefox.
For chrome browser, try Stop YouTube HTML5 Autoplay extension or Magic actions for YouTube.
Thanks for this.
Thanks a lot!
Thx fot the easy help, was already looking at addons who can do this, but this is much better!
You’re welcome Rik. Glad that I could help.
videos at vimeo.com will not play at all if this setting is activated
We don’t at the present that Firefox supports that preference for Vimeo, as mentioned in that article at that time, it does work for YouTube. Seems activating it has break Vimeo or let us know which Firefox version you’re using. Ensure you’re using latest Firefox 52.
Thanks for responding. Yes I’m using the latest version in Windows 10.
The problem still exists. Why doesn’t Firefox provide a setting through
the regular options interface as they do in Android version of Firefox ?
In Android Vimeo works OK. In the settings/advanced “Allow Autoplay” is
set to off
