Works well and is easy to use.

Really well-designed extension. As a developer who is building an extension, this level of usefulness and polish is what I aspire to.

A couple of small quibbles... it doesn't work on Google Maps--causes the site to seize up, probably because it is converting all the colors... also doesn't work very well on certain other sites; for example, if you are trying to view some color-coded information on wikipedia (https://en.wikipedia.org/wiki/Lewis_Hamilton#Complete_Formula_One_results) the colors don't translate so well... silver and grey are almost the same color. Sites that have their own built-in dark mode also render a bit screwy; ex: https://material-ui.com/api/modal/ . The built-in dark mode for most websites is better than the Dark Reader version for that site, which is to be expected.

But these are all really small quibbles... overall the app works really well, it's a joy to use, the ui is crisp and fresh. Really nice extension.

Not only substantially slows down my Firefox, but frequently causes most pages, particularly Nazibook, to stop responding

It work magnificently and you just have to try google map with this thing turned on =D

Tout bonnement excellent

Perfect

Good but I don't like how the extension changes the theme of the browser. Is there any way to just change the webpage colors without affecting the theme?? If you are the developer then please reply.

使用感觉很好，但可惜的是与

// @namespace http://tampermonkey.net/
两个不兼容。。。。。。

Very good. Just need a dark background in about:blank and about:newtab. I have a white page during 1 second before a page is loaded.
