Background image settings does nothing - Firefox

[Louise Maelle Costa Arreguy]

I clicked to report a bug and this opened, so I suppose this is the official way to report bugs...

I run firefox (Firedragon, which is a fork of Floorp, which is a fork of Firefox), and the background image settings just does nothing. Doesn't hide images, doesn't change the looks of the images, just nothing.

Also, kinda bad that there isn't an option to change how background images behave, if I want them inverted or dimmed, for example.
