J'aime beaucoup cette extension, elle permet d'avoir un thème sombre pour la quasi-totalité des sites. L'interface est particulièrement bien faite, et les réglages personnalisables sont appréciables.

Takes the plain white background of websites and automatically changes it to a dark grey/black to match Windows dark theme. Does not break pages with custom backgrounds. Works very well. Very simple idea. I don't know why this isn't a native FF feature yet, but it should be.

Finally there's an add-on for general well-being of screen-staring tribe aka programmers, designers, developers, researchers, editors and all those who spend good part of their day/night staring at computer screen(s). I just love it's customizability, especially different profile per website. It's highly recommended to protect your eyes in case of prolonged computer usage.

Très bonne extension ! Fonctionne vraiment très bien. Ralenti juste un peu la navigation.

Useful extension that lower down the overall brightness of websites. Simple on & off option to disable or enable the main feature of the extension. Memory usage is around 1MB to 1.5MB typically for me as it seems to increase with each active web page loaded affected by the extension.
