All Firefox users should have blocking enabled within a few days.įirefox now implements scroll anchoring, which prevents slow-loading content from suddenly appearing and pushing visible content off the page. Note: We’re rolling out blocking gradually to ensure that it doesn’t break legitimate use cases. Now you get to decide when to disturb the sound of silence. Blocking can be disabled on a case-by-case basis in the site information overlay: This means media (audio and video) have to wait for user interaction before playing, unless the muted property is set on the associated HTMLMediaElement.

Starting with version 66, Firefox will block audible autoplaying video and audio.

Firefox 66 is out, and brings with it a host of great new features like screen sharing, scroll anchoring, autoplay blocking for audible media, and initial support for the Touch Bar on macOS.
