it works in a variety of websites, but be warned: most of my brazilian folks keep it desactivated because it is not lightweight at all

My eyes would like to thank you for keeping them white even after long evening PC sessions :)

You protect my eyes

Después de desactivar la extensión el tema oscuro persiste y no soy capaz de quitarlo

la extension es casi perfecta, pero es muy pesada

nice

The end-all be-all dark mode for everything.

Great add-on! My problem: the add-on increases RAM usage of Firefox significantly (in my case). I have switched to "Dark background and light text" add-on, which works better for me.

Love it its a must. ever since I start make back grounds Dark or Black its so much better for reading for ME.

It is just what I need, The only thing that I would love to see in this add-on is an automatic Turn On/Off by the time zone.
