I can say this is the best extension i ever see.

Finalmente un tema scuro per Firefox che funziona per qualsiasi sito. Una meraviglia per i miei occhi stanchi. Lo consiglio vivamente a tutti coloro che passano parecchie ore al computer.

very good

Amazing extension. Could be more light weight tho.

best till date

I've tried several other darkmode addons/extensions and none compare.
Look no further, this is the least buggy and best one out there.

Awesome extensions, it works out of the box and very configurable... advised
