The website is completely broken with Firefox. Search results do not appear on the screen - you must scroll down to see results. Clicking on the asset images does nothing so they cannot be downloaded.

When using Chrome the layout and interaction works, but even then browsing is a poor experience as only four items can be seen at once so lots of scrolling is needed.

Sheesh... modern web design is a disaster. This sort of collection could really use static pages with labels as links and small thumbnails showing at least 50 items per page.

[Edit] I recommend https://ambientcg.com/ instead as that site is much more responsive.
