The only dark mode extension that doesn't completely F*** my ram usage

I use it since years and I really love it. Websites should always look like what this addon makes 'em look like!

Edit (2021.03): I really encourage the developer to bring a version for Firefox Android/mobile. Please do this favor to your users and "want-to-users".

Right now I'm using dark reader (https://addons.mozilla.org/en-US/firefox/addon/darkreader/) for this purpose. But It just isn't as good, versatile and easy to use for every website as "Dark Background and Light Text" is. It simply doesn't work on lots of sites or breaks the sites. So you have to fiddle around till it somehow halfly works (often if nothing other works you have to use the static mode. Which only makes the background dark but ignores your text colour settings, and makes the text white).

hi can someone tell me how is this extension good or..?
