Why all srcset images being downloaded?
Why all srcset images being downloaded including the largest original size?. On Chrome, only downloads the need-displayed image size so it took only 1.5MB to load my home page while Firefox took 2.5MB. How does this happen?

Could you link to a page that has this problem? I looked at a couple demo pages and watched what Firefox loaded in the Network Monitor* and didn't see any additional images loading before I triggered them:
- https://webkit.org/demos/srcset/ - triggered by zooming in or out a few times
- https://scottjehl.github.io/picturefill/examples/demo-01.html - triggered by making the window very narrow (you have to widen it again after the image switches to read the entries in the Network Monitor)
