1776921 - Dark Mode and Night Mode cancel each other out

Status: NEW

(Firefox for iOS :: General, defect)

Description

[Robin Steuber (they/them) [:bytesized]]

Steps to Reproduce:

1. Turn on Dark Mode in the iPhone Setting app
2. Open the Firefox app.
3. Load duckduckgo.com. Notice that it respects dark mode (I assume via CSS selectors).
4. Turn on Firefox's "Night Mode" setting.

Expected Results:
Duck Duck Go will have a dark background

Actual Results:
Duck Duck Go has a light background

---

It appears to me that Night Mode inverts the colors, even if they are already dark. This is fine as long as the website in question doesn't independently support Dark Mode. I think that one of two things should happen here. Either:

1. When Night Mode is enabled, Firefox should report that it prefers light mode so that it inverts light mode rather than inverting dark mode, or
2. Firefox should take note when CSS selectors are used that depend on dark mode and not apply Night Mode in that case.

I know that we don't control the browser engine on iOS. Given that, are either of these options feasible?
