I installed it, hoping it would make the addons.mozilla.org site dark so I can read without having to squint at the screen that is too bright, but it won't put the site into a dark mode. Can this be fixed somehow?

Super

It saved my eyes.

now a paid app to get all the features. Nope lots of alternatives.

Works brilliantly. Easy to use.

Makes a few sites unreadable, and some have ugly colour schemes, but I can't really blame them. Besides, you can just turn it off in that case.

Great extension. Flips colors naturally while keeping all items as visible as they are in the site's original (non-dark) layout. Very simple to use and highly customizable: You can easily fine tune the darkness intensity. For instance, if you prefer a dark grey theme over a completely black one, it can be easily adjusted. Highly recommended!

The FF version works better than I had expected. It's darkifying many of my favorite websites in manner that looks like the site had its own dark mode. So easy to switch on and off too.

It does what it should, and is customizable to either dark or light mode, or reverse certain sites, or exclude them, or only run on specific sites, but the interface is shit and confusing to set up.

Doesn't work in Linux Mint-Cinnamon desktop, as of this date. Easier to use dedicated Linux apps than waste time for this extension. I tried for 5 days before ultimately un-installing it. On Linux, don't waste your time with this.

Funktioniert von allen "Dark-Addons" hier am besten. Aber es ist dennoch stark verbesserungsbedürftig, da insbesondere die die Zeitleisten in Videos auf vielen Seiten schwer erkennbar sind. Auch sind einige Elemente auf Seiten dunkelgrau auf hellerem grau. Insgesamt ist das Addon aber gelungen.
