How to Stop Autoplaying Videos in Firefox



You can stop autoplaying videos on Firefox by this simple trick. Unlike other browsers, Firefox has a lot of customization options. No, I’m not talking about the Settings or any plugins. It’s inbuilt in the browser.

If you are someone like me, the web can sometimes really annoy you. Especially the automated stuff which happens without telling you anything. Things like autoplaying videos, pop-ups, irrelevant toolbars and forceful blocking of content makes me close tabs straight away. I don’t have a solution for all of those, but Firefox has one for autoplaying videos.

Open Firefox and type about:config in the address bar. Press Enter to open the page. Depending on the settings, Firefox may show a warning about voiding your warranty.firefox-void-warranty

You can safely ignore this warning because what we are going to isn’t going to mess anything on your computer.

You can check the checkmark saying “Show this warning next time” to disable this warning from showing up again. Now, click on “I’ll be careful, I promise!” button to proceed.

You are now on the about:config screen on Firefox. This screen is filled with lots of advanced customization options that are not available in the traditional Settings screen.

Before you change anything here, you should know a few things.

  • All the settings customized by you will have “user set” status.
  • To edit anything, you need to double-click on it.
  • Depending on the type, the acceptable value for a setting can be either a String or a boolean.

Now that you know enough, you can continue messing with the about:config settings in Firefox.

On the about:config page, press Ctrl + F to go to the search bar. Type media.autoplay.enabled. This will list this property on the top for you to edit.firefox-media-autoplay

You can also manually look for it, but that’s slower and counterproductive. Double-click on media.autoplay.enabled to toggle it’s status. It can either be true or false. By default, it is true because of autoplaying videos show on Firefox.

When the status is set to false, Firefox will not allow autoplaying videos anywhere on a webpage.
