I'm using Manjaro Linux with a theme of Adapta-Nokto-Eta-Maia, which is a dark theme, and I set the widget.content.gtk-theme-override to Adapta-Eta-Maia, which is the light version of the theme. I was using FF72 and didn't had any problems until I updated the browser to v73. Firefox just use the dark theme and ignore the theme set in widget.content.gtk-theme-override. Is there a way to fix this problem?
I also tried a maintained gtk-theme, Matcha and there's no changes.
