Meta for making Firefox in-content pages dark. UX is generally positive with this idea given OSes today provide dark modes.

We should add that to the release notes when ready!

If you're using Nightly, you can follow these instructions to enable dark mode support on about: pages :

• Enable the browser.in-content.dark-mode pref
• Enable your system's dark mode in case you haven't
• Restart your browser

If you see any visual bugs, please file them as a dependency for this bug :)

Enable your system's dark mode in case you haven't

Would there be a way to active the dark mode in Firefox (via about:preferences or customizer) without having a system's dark mode?

ui.systemUsesDarkTheme = 1

Which Firefox version is this targetted for?

Can we get an answer on this, please?

Whenever this is ready, I don't have time to work on it this month, but this just needs the most important issues to be fixed and a review to be done, so maybe this could ship in Firefox 70 ?

FINALLY !! It's all fixed in v70 !
Maybe I won't be switching to Edge anymore!
But now you need to add dark mode to your website... every inch of it..

Didn't see view-source: page referenced here:

This!

I guess the XML view also belongs to this?

Since I got just shocked by a white flash, in the middle of the night by this:

Thanks :D

Fixing view-source will mostly fix this as well (bug 1586529).

i use firefox linux version but dark mode is not complete like windows version and menu and settings are still white, i using 72.0.1 64 bit.

I'm Using Ubuntu 19.10 And Firefob 74.0.1 And Error Pages like "Hmm. We’re having trouble finding that site." still in White Background and Black Text, I've tried every thing nothing except ShadowFox Fixed The problem

If you have privacy.resistFingerprinting enabled, you should disable it. Also, make sure you have a dark system theme enabled.

With a dark GTK theme most, but not all pages are now (FF 74.0.1) rendered dark.

Going through about:about, the following pages are shown in light themes:

about:checkerboard
about:debugging
about:home
about:webrtc
about:welcome
about:newtab (same as about:home)

Especially about:home is annoying because it's seen quite often.

about:credits: black text on dark background

Also depends on https://bugzilla.mozilla.org/show_bug.cgi?id=1702933

How can I disable this?

I have set Firefox to a dark theme, but that does not mean, that I want to see websites in their shi*** darkmode.

ui.systemUsesDarkTheme 0 and browser.in-content.dark-mode false seem to have no effect :/

At least some websites allow to turn it off, but they should not even get the info that I use a dark theme...

Wrong bug, see https://bugzilla.mozilla.org/show_bug.cgi?id=1529323. layout.css.prefers-color-scheme.content-override is what you want. 0 is dark, 1 light, 2 system, 3 browser. Extensions can also change this, see that bug.

Ah, this is great :)
Thank you!
