Problem loading the theme mode

[uniwix]

I have pywalfox set to dark and auto fetch at start set to no.
When I open firefox, some elements appears in light mode, some other in dark mode.
However, if I set the the mode to auto, it loads properly. It is the same if I set auto fetch at startup: the theme is right. But because I changed the colors manually, it does not apply my preferences.

The problem is more likely to be a bug loading the theme, but I think that the right solution would be to remember which color was picked in the extension when using auto fetch.
