HTML5 Autoplay Blocker is a Chrome extension designed to disable the autoplay of all HTML5 audio and video elements on websites. It goes beyond merely removing the autoplay attribute by integrating with the media's JavaScript API to restrict media controls and simulate expected behaviors. This ensures normal functionality across all pages while effectively preventing unwanted media playback.

Since version 1.2, the extension's code has been entirely rewritten to resolve major issues and improve reliability. Users are encouraged to provide feedback if any new bugs or problems arise. This extension is an excellent tool for anyone looking to take control over their web browsing experience by stopping automatic media playback.

It just works ;)

Doesn't work on YouTube. If I click a video, it immediately starts playing.

It works as expected in my Windows 11 Edge browser. This extension is reliable.

Extension safety

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

HTML5 Autoplay Blocker requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk impact analysis details

Risk likelihood

Risk likelihood measures the probability that an Edge add-on may turn malicious. This is determined by the publisher and the Edge add-on reputation on Edge Add-on Store, the amount of time the Edge add-on has been around, and other signals about the Edge add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing an Edge add-on.

HTML5 Autoplay Blocker has earned a fairly good reputation and likely can be trusted.
