As a preliminary comment, if you use a "High Contrast" theme on Windows, you can instruct Firefox to ignore that. See: Disable high contrast mode in Firefox.

Firefox 95+ is taking more and more cues from your toolbar area theme for how to style other aspects of the browser. There is a setting for some of these, but not all of them.

(A) Right-click context menus, toolbar drop-down panels

Starting in Firefox 89, these would flip to a dark background if the text on the inactive/background tabs was white or light. Firefox 96 has extended this adaptation to more parts of the browser. I have attached a composite screenshot of what Firefox considers a "Dark" theme (light text) and a "Light" theme for reference. It's difficult to say exactly where the line is. As far as I know, the only built-in way to change this is to change your toolbar theme. (The other way is the not-officially-supported userChrome.css file route.)

(B) Built-in pages, and websites that have light/dark responsive themes

Starting in Firefox 95, Firefox would inform pages that you preferred a light/dark theme based on your Firefox toolbar theme instead of your system theme. There is a way to decouple your page (content) theme preference from your toolbar theme. At this point, it's only available through the back door...

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button accepting the risk.

More info on about:config: Configuration Editor for Firefox. The moderators would like us to remind you that changes made through this back door aren't fully supported and aren't guaranteed to continue working in the future.

(2) In the search box in the page, type or paste layout.css.prefers-color-scheme.content-override and pause while the list is filtered

(3) Double-click the preference to display an editing field, and change the value to whatever you prefer from the list below, then press Enter or click the blue check mark button to save the change.

  • 0 => Force a Dark background
  • 1 => Force a Light background
  • 2 => Follow the System theme (default in Firefox 94)
  • 3 => Follow the Browser toolbar theme (default in Firefox 95+)

The about:config page should immediately reflect your saved change.

Works beautifully for Firefox maintenance pages. Not at all for webpages. How about a dark background for webpages?

On the other hand, every time Firefox updates, my friend's version switches everything she see to dark more, which is not her default setting.

Something's broken here.

Intelligently modifying all the colors on a site that doesn't auto-switch themes is hard. There is an add-on for that, and I don't know whether anyone wants to take it on as a built-in feature.

Does she use the built-in "System" theme? If she hasn't tried the "Light" theme, that might work better.
