After the fix it's working great!

Super extension! I ask you to consider the possibility of making a hotkey for switching the (dark<=>light) mode and adding a filter for solarized dark theme (dynamic if possible).

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

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!

Great idea. Loved it

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