# Browser Dark Mode

Dark Mode luckily has become a thing also in the non-unix world. Finally
browsers can be used with dark interfaces and websites can have
alternative color schemes.

However, in other operating systems, there is a global toggle for dark
mode, which also switches the browser into it. This is not the case on
linux and unix systems.

## Chrome / Chromium / Iridium

Chrome and Chromium starting with version 73 can be tought to start in
dark mode:

<pre>
$ chrome --enable-features=WebUIDarkMode --force-dark-mode
</pre>

Then go to chrome://settings/?search=themes and switch the theme to
"Classic".

## Firefox

Firefox learned the dark mode in release 70.

  0. Go to "about:config"
  1. Enter "ui.systemUsesDarkTheme" into the search bar
  2. Click "Number" and then "+"
  3. Enter "1" and click the check mark

Right click on a free spot in the icon bar and select "customize". At
the bottom left of the screen, you can switch to a dark theme.

Note: If you've set privacy.resistFingerprinting to "true" the CSS dark
mode switching won't work. Kudus to
[@andinus@tilde.zone](https://tilde.zone/@andinus) for figuring this out.

There you go, both browsers are in dark mode now. The UI should be dark
and also websites that support the `@media (prefers-color-scheme: dark)`
directive should make use of it.

You can test it on my webpage ([https://codevoid.de](https://codevoid.de)). The
light version has a light gray background and a blue font. The dark version has
a dark gray background and an orange font.

## vim-browser (vimb)

<pre>
$ echo "set dark-mode=true" &gt;&gt; ${HOME}/.config/vimb/config
</pre>
