Details

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:81.0) Gecko/20100101 Firefox/81.0

Steps to reproduce:

View any internet page with many images.

Actual results:

Images are loaded only when images come into view. Page view is not smooth as images are being loaded as we scroll. Scrolling a long page with many images is extremely jerky.

Expected results:

Unless the image is very large, loading lazy should not be invoked. For example only lazy load images which exceed 3000px width or height.

Hiro, could you take a look?

This is truly a dup of bug 1618240.

Note that there is an ongoing discussion about when a loading="lazy" image should load, and also note that as far as I know Chrome has changed the behavior since they were complained it's too eager.
