It surely has pretty design and smoothly darkens most of common sites BUT it slows down page loading for even MINUTES. Firefox 61.0, wire connection, works with speed-of-light without add-on.

It creates aesthetically better pages then any other extension and works excellent on most sites. However, as others mentioned, it indeed slow page loading (sometimes significantly)

I experimented with a few different "dark mode" extensions and this one gives the nicest result.

Nicely helpful for shading pages and helping to reduce eyestrain.
Thank you,

Thanks for this add-on, I can't browse without it! I love to be able to swith it easily between light and dark !

Muy bonito y funciona en la mayoría de páginas.

so far I really love the app

Es muy bueno, pero comúnmente ralentiza las búsquedas y genera problemas de compatibilidad con ciertas paginas, por ejemplo Gmail.

Bonne extension. Je confirme, c'est plus agréable la nuit. Merci au dev.

Good

Does a great job of styling, but at the cost of page-load speed. Pretty sluggish performance while using this add-on.

Unbeatable, tried man and always found a bug or something not working correctly. Dark Reader nailed it!

Bonjour, un grand soulagement pour mes yeux! Merci.
