It just doesn't work on some sites like the addons.mozilla.org one

Great add-on for dark mode with many customable settings. It works nearly everywhere. However the best looking mode "dynamic" is quite performance intensive and it does not work everywhere; e.g. Azure DevOps, the left menu and the top part stays unchanged.

Works best compared to the other dark theme extensions!

Best dark extension for Firefox !

This add-on helps my eyes a lot. There are other dark theme add-ons that are worthless. Bright white text on a totally black background is definitely not good. Dark Reader is made with effort so that i both looks good AND works good.

The best dark-mode add-on in Firefox!

Funciona perfecto

Great work!

Very good extension buddy
