In macOS (Tahoe), how to get Firefox to follow system dark/light settings that INCLUDE the web pages themselves?

Firefox Browser appearance

macOS Tahoe, Firefox 152.0.3 macOS settings include "Appearance - Auto"; i.e. system switches from light to dark at sunset. While the "top area" (tabs, address bar, bookmarks bar) of Firefox follows this - some of the pages themselves do NOT???

I found this website which was at top of the search results. I tried to follow it, but it seems to be badly outdated in certain key respects: esp wrt a setting called "ui.systemUsesDarkTheme" in about:config. I set this to "True", but may have screwed this up!! First question: Should I "reset" this somehow?

Finally: To get at the primary question, there are two "sub-questions" that may explain my confusion more clearly:

1. Is there no ***simple way*** to get Firefox & webpages I view to follow macOS Light/Dark appearance?? What are the CORRECT steps?

2. Do individual webpages have the ability to "decide for themselves" whether or not they will adhere to the system light/dark settings. This may well be an officially "stupid question", but while "most" webpages remain "Light" (including this Support page), a few pages appear dark.

Hi

As a first step, I would reset that about:config setting. Not really needed and could make things more complex later on.

Websites may have settings to either use light, dark or system colour themes. This is a per website setting. Setting it to the system option will follow macOS. The default theme in Firefox will also follow the system setting.
