On FF for iPadOS

WTF is this? There's no dark mode support (hence the use of the light version). Did you turn some option on to get this?

Reclassified as a feature request. As discussed in Lausanne, that's something we want but not a priority.
The screenshot depicts an automatic mode of FF. We'd prefer something better based on @siemsie color palettes for light and dark.
