1602175 - New tab page remains in light color scheme when Adwaita-dark GTK theme is used

Status: RESOLVED DUPLICATE of bug 1546540

(Firefox :: Theme, enhancement)

Description

[Alex Dueppen]

Attachment: The bugzilla uses the dark theme whereas the new tab page does not.

User Agent: Mozilla/5.0 (X11; Fedora; Linux x86_64; rv:71.0) Gecko/20100101 Firefox/71.0

Steps to reproduce:

With a dark GTK theme such as Adwaita-dark, use Firefox on Linux

Actual results:

The new tab page uses a light theme, unlike the rest of the browser's UI. The preferences page and websites using the prefers-color-scheme media query use a dark theme as expected. The new tab page also properly uses a dark theme when Firefox's included dark theme is used, but I don't use it since it causes the UI to clash with the color scheme of the GTK theme.

Expected results:

The new tab page should respect the prefers-color-scheme query when using a dark GTK theme.

Hi Alex,

I was able to reproduce this on Ubuntu 18.04.3 LTS using:

• Firefox Nightly 73.0a1 (2019-12-16) (64-bit)
• Firefox Beta 72.0b5 (64-bit), Beta 72.0b7 (64-bit)
• Firefox Release 71.0 (64-bit)

By default, the new tab page will display as a light theme. You need to enable the Dark theme from about:addons so the new tab page gets displayed in dark mode:

Steps:

1. Type about:addons
2. Go to Themes
3. Go to Disabled section
4. On the Dark (disabled), click on the three dot menu and click "Enable".

I'll mark this ticket as an Enhancement for Firefox to open a new tab in dark mode as default, when using a dark GTK theme such as Adwaita-dark.

Regards,
Virginia

This is Firefox UI page, moving.
