Stop Autoplay — Block Video Autoplay

Stop Autoplay prevents videos from playing automatically when you load a page. Autoplay videos consume CPU, GPU, and network resources even when you are not watching them — and in background tabs they can cause stutter and drain battery. This feature is free and requires no configuration beyond choosing your preferred level.

How It Works

SuperchargePerformance intercepts video autoplay behavior, preventing video elements from beginning playback without a direct user interaction (clicking play). At the “Allow Common” level, an allowlist of major video and conferencing platforms is exempted so your intentional media experiences are not disrupted. At “Block All”, blocking applies universally to every page.

The feature targets the autoplay behavior specifically — videos remain fully functional and play normally the moment you click them.

Settings

The default is Off. Enable this feature if unexpected video playback on general websites disrupts your browsing.

When to Use This

• News sites, social feeds, and ad networks that trigger video the moment you land on a page
• Background tabs that start playing video without your interaction, causing audio overlap or performance slowdowns
• Battery-sensitive sessions where you want to avoid unexpected video processes
• Any situation where autoplaying video catches you off guard in a quiet environment

If you experience video stutter on specific platforms like Twitch or YouTube, see the related library articles — stutter on those platforms has different causes than autoplay behavior.

Privacy

Stop Autoplay operates through local browser policy settings. No information about which videos were blocked, which sites you visited, or any playback data is transmitted anywhere. Everything runs on your device.
