I would like to see the text fields change to dark grey/black. Also a darker shade on the URL bar would be desired.
Currently as it stands, the system default is better as far as a dark theme goes.

After FF update to v119.0 all menus and dialog boxes turned light.

Die vermutlich schönste Firefox dark Version des Firefox Logos.

I will use this theme until my death.

the only firefox theme that really matters. :/
