I have set my Galaxy S22 to use dark mode in the evening. Firefox doesn't seem to realize that it has changed to dark mode. Right now I can choose follow device theme and it goes to light mode, even while the phone is in dark mode. Choosing dark mode makes it dark. Choosing follow device theme makes it light again.

I tried to toggle dark mode off and on in my phone while in the Firefox settings menu was open and now Firefox shows dark theme while follow device theme is selected. I think the same happened yesterday as well.

Maybe Firefox has trouble registering that the phone switches theme on a schedule.

During daytime when my phone changed to light theme as scheduled I experience that Firefox shows dark theme when set to follow device theme. I can choose dark and it becomes dark, and choosing follow device theme makes it dark again.

Turning dark mode on and off in my phone makes Firefox light again.

So it definitely seems to be Firefox that is unable to correctly detect the scheduled changes of dark mode. I have Galaxy S22 unlocked nordic version with the latest updates for both the phone and Firefox.
