Images from KDE Store, Pling do not load at all

Hello everyone!

This is a weird problem. For some reason, I’m not seeing the images on KDE Store and Pling pages. Thumbnails, profile pics - the images just don’t load. There’s only the icon of a broken image instead.

I have tried reloading, restarting browser, but nothing works. I am on KDE Neon and my browser is Firefox 69.0.1.

Interestingly, everything’s fine on Windows. What could be causing this?

This seems to have something to do with Firefox, because in Chromium the problem is not there.
