Steps to reproduce: This is a request for support for the loading attribute for video elements, which would support lazy-loading for video. The loading attribute for video would use similar conventions to img and iframe, where the attribute has precedent, and provides performance benefits. It would have possible values of eager and lazy. When the loading attribute value is lazy, loading of any video or poster image data, as well as autoplay playback, must defer until layout is known and the video is in the viewport. Issue tracker ticket https://github.com/whatwg/html/pull/11980 Mozilla Standards Position: https://github.com/mozilla/standards-positions/issues/1325 Actual results: Firefox does not currently offer built-in lazy loading of video. Expected results: Firefox should lazy-load video elements that have a loading="lazy" attribute.

Steps to reproduce: This is a request for support for the loading attribute for video and audio elements, which would support lazy-loading for video and audio media. The loading attribute for video and audio would use similar conventions to img and iframe, where the attribute has precedent, and provides performance benefits.
