1459504 - Allow changing the content area background/text colors

Status: NEW

(WebExtensions :: Frontend, enhancement, P3)

Description

[Tim Nguyen :ntim]

Selectors it should target:

- #tabbrowser-tabpanels (depends on bug 1440865)
- #customization-container
- ???

+ in-content pages (can be a separate bug, since that work depends on bug 1444459)

Use case: create a full dark theme and reduce the amount of white as much as possible.

The properties can be called: colors.content_area and colors.content_area_text.

Since the built-in dark theme uses a different background for #tabbrowser-tabpanels and #customization-container, it might be worth creating different properties for the customize mode, not sure.

Themes generally can't access web content, and that's where this default background mostly matters.

I believe the main use case here is extensions making web content dark. We can probably provide an API tailored for that, independently from webextension themes.

See comment 1 for why this should not be part of the theming API.
