Firefox will flip content of my Figma Sites Page

When publishing my Figma Sites website, since today Firefox (Desktop) will flip the content order of my site – so the last element is displayed first, and so on. That’s neither the case in any other browser (such as Safari or Opera) nor in Firefox on mobile, nor in the preview in Figma Sites. But i tried it out on Mac and Windows. Seems to be a global Firefox Desktop problem. Why is that?
