A must have! Does not affect Firefox performances and provides beautiful dark modes for websites that does not integrate them natively... A super eyes saver :-)

excellent add-on a must

only thing is that is will slow down ur computer but not to much

This extension is such a relief for my eyes. No more having to endure all those websites with awful #ffffff'ing eye-searing white backgrounds!

I can now use a more subdued off-white background colour which is easier on the eyes, switch to full dark mode if reading in low light, or configure the colour palette even further if I want. My eyes are truly thankful!

Slowed down the performance in certain sites which translated into sites not loading completely. Good overall but heavy on resources.

Great idea. Loved it

Absolutely fantastic productivity addon. A MUST install for our family. Well done Mr. Shutau !
