How do I toggle the mode on and off?

This is a very nice and good theme. Love it!

Darkmode is for my Eyes better, but that are some points tooo dark. i wish a dark-gray option.

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

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

does have
