cumple muy bien en general

It's great but I wish the there's some kind of whitelist or blacklist instead of global toggle.

每次顏色都得重新設定，非常麻煩，能否弄個備份？

It's faster than Dark Reader, but also works worse.

I really like the dark background theme however I have found it really slows down the FF Browser. I would like to be able to just enable it when I want, but I haven't figured out how to do this. I'm probably missing the instructions that are right in front of my face. At any rate, I like the dark background but I'm removing it for now because of how it slows down the browser.

it exactly works like the name. it's lightweight and does one thing great! although dark reader has better looking options, it's 10 times as bigger and i consider it bloated.

***** dafür das ich meine gewohnten Farben genau einstellen kann.
* dafür das alles von Mozilla mich nun weiß blendet, nicht nur die Startseite sondern auch alle Webseiten und Foren. Bekommt man dafür die "Official-Add-on Plakette"? Buuuuh, ich bitte um etwas mehr Kampfgeist..

nice and simple but is doesn't have a white or black list though.

Fairly nice and working well. I have been enjoying using it. One improvement which I would appreciate is that way it renders text/search fields & icon links. Now it is often wrapped with a white border with rounded corners and does not match back to the interface of some websites (e.g. DuckDuckGo, social media sharing icons). It also disable/hide some icon links (e.g. on Medium when trying to clap hands or saving an article, icon buttons on the left) and emoji display (on Facebook posts).
