Built-in dark mode for web contents

[batata]

I love extensions like Dark Reader that automatically transform any website with a dark theme. The way they do this is by injecting many new styles into the DOM, it works but there is two main drawbacks to this method :
- there's a latency that makes contents blink
- it reduces performances on some websites by a lot

So It would be great if there could be a built-in low level solution (directly in web render?) that would swap colors on the fly without editing the page styles and thus would solve the two aforementioned issues.

just implement this, for the love of God.

Firefox is literally the only browser on Android that doesn't have a built-in dark mode for websites.

don't complaint later if you start losing your users. 😐

Hi,

Thank you for bringing this Speedometer concern to our team. I'm on the Performance team at Firefox and I believe the reason your Speedometer score is worse is because of an issue with the extension Dark Reader. We can work with the Dark Reader team to make their extension quicker but there is only so much we are limited from our end. Thank you again for raising this!

@perladuenas1thank you and I believe I speak for everyone here when I say that we appreciate everything you do to improve dark mode on Firefox. However, as @batata said in his original post, as much as we love extensions like Dark Reader, they're inferior in that they inject many new styles into the DOM, thereby performing slowly and unreliably. Instead of trying to perfect what is inherently bad, IMHO it would be preferable if the team at Mozilla developed a built-in low level solution.

Firefox team should look at how Samsung does this. The Samsung browser's built-in unobtrusive dark mode for websites is a big reason why I'm not using Firefox on Android right now, even though I use Firefox on desktop.

Add me to the line of people waiting for native dark mode support in Firefox. It's literally the only reason I haven't switched to Firefox as my main browser on desktop and Android.

Why'd they be bothered with such feature that every browser have, when they can simply rely on 3rd party not so reliable add-on, they too lazy to work on such feature.

Literally could be done with a more intelligent css; even in complex cases.

Figure out brightness; levels of all elements and tune them down and or make them the opposite without destroying visibility and imagery;etc

Could even have color schemes and variations as OPTIONAL; options.

Before you even see the page; it should already have completed the entire process; so it's a page like any other; as if it never happened...

This has to work on every website; from YouTube, to BandCamp to some random persons website; etc.

If firefox developers can't put that on high alert and do that; then am personally shocked at; how far mozilla has come; perhaps it's like a roller-coaster of circumstance; some periods are amazing; others are not.

I'm not demanding change; am merely stating confusion and discomfort; with questionable designed extensions and difficulties with built-in darkness.

@Jon 

Its been almost 3y since this was brought up, over 2y since it first journeyed.

I have escalation schedules that ring during night. And first thing i do in the middle of the night is give my eyes a burn in with about:profiles, since profiles UI also still isnt implemented, and no theme covers about pages.

Come on guys...

It's so sad that built-in dark mode is still not supported on FF both on the mobile and the PC platform.

Samsung Internet and Edge already support this feature, and it works really well. Most importantly, a built-in dark mode won't slow down the browser like other extension do, which means a lot to better browsing experience.

I think I will be switching to a browser that supports native dark mode at this point, have been waiting 2 years for a feature that Edge could implement before Firefox...
