The only reasonable solution is 1, IMO. Dao, Gijs, here's a proposal:

> The `prefers-color-scheme` of a page (and all its subframes) loaded in a `<browser>` element depends on the used `color-scheme` property value of that `<browser>` element.

That should do the right thing by default, and for the tabs the front-end would have:

```css
#tabbrowser-tabpanels {
  color-scheme: light;
}
@media (-moz-content-prefers-color-scheme: dark) {
  #tabbrowser-tabpanels {
    color-scheme: light;
  }
}
```

Or something of that sort. That way the front-end is effectively in control of the prefers-color-scheme values of everything. That means popups and sidebars get consistent prefers-color-scheme values, too. What do you think?
