This extension used to work flawlessly... years ago. Now, it's a broken piece of junk that routinely breaks pages, causes major performance issues with FF and tabs to crash, and makes text/images so dark as to be unreadable. I'd rather suffer through the blinding light, thanks.

llevaba usando esta extensión años. Pero he detectado que cada vez que se usa esta extensión los requerimientos de potencia a las GPU son enormes. Os invito a abrir una web con un numero importante de enlaces. y abrir en paralelo la monitorizacion de la carga en la GPU. activar y desactivar dark reader moviendose hacia arriba y hacia abajo en la propia web(sin necesidad de click nada) y comparar como de un 20% pasamos a un 80% en la carga de la GPU (mi grafica es una RX6700XT) .

On the visual side this add-on works very well. BUT it seems to have a SECURITY ISSUE, since when it is activated certain website logins (e.g. a bank) don't work anymore. I wonder how this is possible since the add-on supposedly only alters a websites colours.

老眼で字が2重に見えたりしていたけどこれにしてから、ちゃんと見えるようになった。
サイトもキレイだし気に入りました。

I do not understand how this can be a recommended add-on. Yes, it does the job and it looks pretty and all that. But I have never had an add-on that made my pages freeze up and cause my browser to crash before this. It's almost impressive to see how they managed to mess up such a simple thing. Refreshing pages take forever and when I resize my windows all of my tabs lock up, stuck between the original width, to the new width and everything in-between. How do you manage to make something that is supposed to only change the appearance but somehow invents more problems??

Works ok but not with scanning QR-code. Therefor you got only 3 stars. I got the QR-code in the color GREEN. My bank-app did not recognize the QR-code. Maybe an option to change your code when there is an QR-code to be scanned.
