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.

We all are anxiously waiting for this feature....

In the meantime , I've been using "Ultima Dark" extension for dark mode of websites. It works better than the other extensions and faster. ( I tried 4 other extensions before that aren't very good) It is on the Firefox store to download. Maybe Firefox uses the extension mode rather than an internal setting that might conflict with Gecko.  HTH
