How to Stop Autoplay Videos in Firefox

How many times have you entered a website in your Firefox browser, only to see an annoying video pop up?  Do you want to disable videos from playing automatically in your browser?

How to Stop Autoplay Videos in Firefox

If so, we’ll show you how to stop autoplay videos in Firefox. You’ll also learn how to prevent videos from playing automatically in other desktop and mobile browsers, as well as disabling the autoplay feature in some social media apps.

How to Stop Autoplay Videos in Firefox?

Firefox has a built-in feature that can stop videos from automatically playing every time you enter a website. All you have to do is go to browser settings and block audio and video from playing automatically.

  1. Launch Firefox.
  2. In the top-right corner of the screen, click on the three horizontal lines.
  3. Click “Options.”
  4. Go to “Privacy & Security.”
  5. Scroll down to the “Permissions” section.
  6. Click “Settings” next to “Autoplay.”
  7. Click on the small arrow button and select “Block Audio and Video.”
  8. Click “Save Changes.”

Great! Now, pop-up videos shouldn’t play automatically.

Using the Firefox Configuration Editor

If videos keep popping up on some websites, you can use a more advanced method. Firefox Configuration Editor lets you fine-tune your surfing experience in their browser. One of the options it provides is disabling autoplay videos completely.

  1. Open your Firefox browser.
  2. In the search bar at the top of the screen, type in “about:config” and press ‘’Enter.’’
  3. Click “Accept the Risk and Continue.”
  4. Type “autoplay” in the search bar.

Note: In steps 2. and 3, don’t type in the quotation marks.

Now, you’ll see the list of autoplay preferences in Firefox. You can toggle the true/false value by using the toggle button. As for values that have numbers, use the pencil button.

This is the list of preferences and their supposed values:

  • media.autoplay.default = 5
  • media.autoplay.blocking_policy = 2
  • media.autoplay.allow-extension-background-pages = false
  • media.autoplay.block-event.enabled = true

You need to edit these specific preferences for all videos in your browser to stop playing automatically.

Note: To check if this is working, go to YouTube and click on any video. If you did everything right, the video shouldn’t start automatically.

How to Stop Autoplay on Firefox With an Extension?

If you don’t want to bother with the Firefox Configuration Editor, you can add an extension to your browser that will prevent HTML5 videos from playing automatically.

  1. Go to Disable HTML5 Autoplay page.
  2. Click “Add to Firefox.”
  3. In the pop-up menu, click “Add.”

Success! The extension will now automatically block HTML5 videos in your Firefox browser.

How to Block Autoplaying Content Automatically?

Sometimes you only want to block social media content. It can be annoying (and embarrassing) when a video suddenly starts playing full blast while you’re casually scrolling through your Facebook, Twitter, or Instagram.

How Do I Enable or Disable AutoPlay Video on Safari Browsers?

Safari is your default browser on Mac, iPhone, and iPad. Like Firefox, it enables you to configure your AutoPlay preferences. You can set these preferences for a single website or all of them.

Mac

Disabling AutoPlay on a single website (e.g. CNN) can sometimes be a better option if you just want to stop videos from automatically playing on one specific website.

1. Open the Safari app.

2. Go to the website where you want to disable AutoPlay.

3. Click on “Safari” and choose “Settings for This Website.”

4. In the “Auto-Play” setting, select “Never Auto-Play.”

Now you’ve blocked a specific website from playing videos automatically in Safari. To revert this setting, simply go to the same website and follow the path “Safari” > “Settings for This Website” and select “Allow All Auto-Play” in the “Auto-Play” setting.

If you want to disable all websites from playing videos automatically in Safari, do the following:

1. Launch Safari.

2. Click on “Safari” and select “Preferences.”

3. Go to the “Websites“ tab and select it.

4. In the left sidebar, click “Auto-Play.”

5. At the bottom right corner of the dialog box, select “Never Auto-Play” in the “When visiting other websites” setting.

Note: To enable all websites to automatically play videos, go back to step 6. and select “Allow All Auto-Play.”

iPhone/iPad

There is a setting that lets you stop videos from automatically playing in all apps on your device. Unfortunately, this is the only way to disable AutoPlay video in Safari.

4. Toggle off the “Auto-Play Video Previews” option.

Note: If you want to revert the Auto-Play setting, go back to step 4. and toggle on the “Auto-Play Video Previews” option.

This setting applies only to apps that are native to your iPhone, like Safari and Camera. If you use a third-party browser (e.g. Chrome), videos will play automatically. So, you’ll need to configure autoplay preferences in that browser.
