Parallax Images not loading on Firefox

Hi,

I think with the latest update, the Parallax section images dont load on Firefox any more. I checked the demo site as well and dont see the parallax section loading there as well as in the attachement. However on Chrome or edge or safari things are fine. Could you please look into and suggest an alternate?

Hey there

Images are appearing normally for me, I can’t see any problem, here is the screenshot:
