Autoplay Stopper Chrome Extension: 3 Levels, Free

Unexpected video is one of the fastest ways a tab eats CPU and network while you are not even watching. Stop Autoplay is the SuperchargePerformance autoplay blocker that handles it: videos and audio no longer start by themselves, and you choose how far to block.

What Stop Autoplay Does

Stop Autoplay is installed by the SuperchargePerformance extension. It stops video and audio from starting on their own, at whichever of three levels you pick:

• Allow Common keeps the major video platforms and conferencing tools playing and blocks autoplay everywhere else.
• Block All blocks autoplay on every site except the ones on your whitelist.
• Off turns the feature off entirely.

The core of the extension, Stop Autoplay included, is free. The PRO tier is a one-time payment rather than a subscription, and it is not needed for this feature.

Setup in Three Steps

1. Install SuperchargePerformance. Stop Autoplay ships in the free core, so there is nothing extra to add.
2. Open the popup and turn Stop Autoplay on. The feature is off by default, so nothing happens until you enable it.
3. Pick your level. Allow Common is the milder choice; Block All is the strict one. Sites on your whitelist bypass the feature completely, whichever level is active.

What It Controls

The default is Off. The whitelist applies to the whole feature: a site you add to it can autoplay again, and tab suspension is bypassed there as well.

On YouTube, the next video in a queue does not auto-start: it stays frozen until you click play. On X and LinkedIn, feed videos pause as they scroll into view.

How It Differs From Chrome’s Built-in Setting

Desktop Chrome has no autoplay setting. The Sound control (Site settings > Sound) offers three options: let Chrome choose, allow sound, or block sound, plus per-site allow or mute exceptions. There is no middle level that keeps video and meeting sites working while the rest of the web stays silent.

Stop Autoplay adds that middle level and a per-site whitelist. Muting a site in Chrome only silences it: videos still start and play, because muted autoplay is always permitted. It also does not fix stutter. If a video stutters after you start it, that is a different problem, and the library articles linked at the end of this page cover the Twitch and YouTube causes.

The limitations come with the blocking. Muted preview videos on news sites, X, LinkedIn and other sites outside the allowlist stop under Allow Common; the social sites that are on the allowlist keep playing. And because the feature is off by default, nothing is blocked until you switch it on.

Permissions, Privacy and Edge

SuperchargePerformance declares the storage, tabs, alarms, declarativeNetRequest and scripting permissions, plus host access to all URLs. Storage keeps your levels and the whitelist. The rest is what the extension as a whole uses: the blocking rules, the timers, and bundled scripts that run inside pages, including the autoplay code.

The extension collects zero telemetry. Nothing about which videos were blocked or which pages you visited ever leaves your device. Uninstalling opens a feedback page on superchargebrowser.com; it carries no browsing data.

SuperchargePerformance is also listed natively on the Microsoft Edge Add-ons store, so the same feature works on Edge.
