I’ve just installed Lubuntu 23.04 this morning, and I went to configure my system with a dark theme. I installed kvantum and chose a dark theme there, and then selected kvantum-dark as my widget style, kvantum as my LXQt theme, and for GTK style I selected Arc-Darker for both GTK 2 and 3.
Despite doing this, and restarting my system, when I start firefox (with it configured to use the system theme), it chooses its light color theme instead of dark, and the address bar and tabs at the top remain light even if I explicitly set firefox to be dark.
What else do I need to do to actually get apps to respect my choice of a dark theme?
Here’s an image of what firefox currently looks like when I force it to use a dark theme: screen hosted at ImgBB — ImgBB
As a side note, I was not able to upload the image into this forum post; I got a pop-up indicating that an error occurred when I tried to paste it in.
