Some sites have contrast problems, but for the majority of sites, it works really well! Must have extension for sure!

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!
