Details

Steps to reproduce:

Go to about:preferences#general and set Website appearance to Dark.

Actual results:

ComingSoon pages load in light mode. Example URL: https://www.comingsoon.net/games/reviews/1247696-garbage-pail-kids-mad-mike-and-the-quest-for-stale-gum-review-ps4-worth-buying

You have to manually click on the icon at the top right corner of the page to enable the dark theme, which sets a simple cookie. Users who have configured Firefox to delete cookies automatically have to keep doing this again every time they open the site.

Expected results:

Please reach out to ComingSoon to ask them to respect prefers-color-scheme.

The Bugbug bot thinks this bug should belong to the 'Firefox::Theme' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Raul, this isn't a Firefox bug, let alone a Firefox theme bug. This is an issue with the site, which doesn't respect prefers-color-scheme.

As you can see on 1794320#c3, the component I had selected is the correct one: Web Compatibility.

Flags: needinfo?(raul.bucata)

It seems that their design has been changed since when I first created this report. I don't see a button to toggle the dark mode anymore, so apparently they were just testing it for a limited time.

From the report, I understood that the Dark theme fails when activated from the browser. Was the dark theme activated from the browser, or there was a button on the page to do that?

The Website appearance setting doesn't force any site to be dark. It just uses prefers-color-scheme to politely request sites to use their own dark themes, in case they have one.
