I've used this for about a year+ on both Chrome and Firefox. It does an excellent job of converting most websites to a dark theme. It really reduces the strain on your eyes in a dark environment. I'm very happy with this app.

i have been using firefox for a very long time, but dark mode was very helpful during my online classes, where i had to study online for very long hours. dark mode is good for eyes and also saves battery. but it is slowing down my browser so i have removed it.

好用

In general, the addon is very useful, but it causes an error on my working zimbra mail server that prevents the page from loading.

This addon is a big joke especially on mobile devices. Bad optimization and the fact that the settings don't really work at all, I'd have to manually fiddle all the pages I visit if I wanted this app to work like it's supposed to work. Kinda big job to do that on mobile device, just gonna uninstall this and waiting for the day team Mozilla bakes a dark mode themselves in Firefox OR gives us more addon options like on desktop version.

slowed down my whole computer, uninstalled.

I've installed, uninstalled, restarted Firefox but Dark Reader is MIA. Perhaps I am doing something wrong but I cannot fathom what.

Works fine on some sites. For example on Youtube. But on other sites the tab hangs. And the whole browser slows down.

Other dark mode add-ons are sub-par. This one really keeps the page the same and just adds dark mode, like the developers of every site meant it to be like this. Very very nice, can not browse without it anymore

使用中表示が非常に重くなるページが出てくる。（価格コム等。）DarkReaderをオフにした状態だと違和感なく開けるが、広告が多かったり複雑でごちゃごちゃした作りのサイトの表示は厳しいかもしれない。
