Great tool. Works on a lot of websites. Cannot understand why this hasn't a better score. Yes, it does not work on any website, but it should work for the majority and is a big help for me.
Absolutely recommendable.

conflict with webpage "24h.pchome.com.tw"
(webpage no output, refresh page not work.)

it is kind of working, but I see nothing, just gray screen on the page and no text anymore, when cliking on something to write and so, that's why so low rating

the best darkmode add on I have come across.

Ugly effect

It uses the negative effect to act as a dark mode. Not as painful to the eye, but it doesn't look good.

BEST SO FAR

Great: Many Settings Options

Needs to be prioritized at Implementing:
1. Quick Settings available at clicking the icon or with shortcut
2. Different methods of applying darkmode for performance reasons of different kinds of websites like:

addons.mozilla.org/en-US/firefox/addon/dark-background-light-text/?utm_source=addons.mozilla.org&utm_medium=referral&utm_content=search

Helpful

What I like: I can set my very own, very simple filter, and that is all I have ever wanted a dark mode extension to do so as to replace my having to apply the style change myself to pages that I want not so bright.

What I don't like and makes this extension a no-go for me: The developer makes getting to the extension's preferences way harder than it needs to be (I have to access it from the AOM page after getting to it in one way or another every time I want to update a setting for this extension - why? At least give us a right-click to a pop-up or the options page...); and, the exclude functionality does not work with domain names alone - subdomains must be added separately, the label for the exclude list field does not mention this, and it is really annoying on large sites or sites that offer multiple services through various subdomains (at least there is a context menu item to disable the extension on a page but only after it has already executed on the page).

doesn't work

made me unable to read most text on websites and made lots of buttons look very weird. would not reccommend.
