Midnight Lizard vs Dark Reader Comments
Positive comment by Sam Lander · May 29, 2024
Similar extension size as Dark Reader, but offers much more customization levels. It allows you to fine tune things like background image saturation and size.

If you want something smaller, you can just use an inversion extension, or even just change a setting on many browsers to invert.

might be a little worse in its implementation but at least it doesn't feel like adware, and i can apply custom colour schemes like dracula
