Firefox becomes unusable as I only have 4 GB of RAM and it keeps freezing and is otherwise slow with this. Manjaro Linux OS. When disabling Firefox is normal again.

A great extension that's unfortunately brought down by crippling performance issues.

Excellent pour la lecture nocturne et protège les yeuxde la lumière intense de l'écran.

This is excellent. Smart dark mode everywhere.

Love it. would be nice if it could automatically be activated after sundown (on a certain time).

My life would not be completed without this extension, thanks to you very much for you hard work !!

it's odd because on some specific website it will pop a tip which writes "darkreader is slowing your website", and then the firefox stuck for a while.
Besids that issue, it's pretty good add-on.

Parfois, il peut être utile de désactiver temporairement le mode sombre pour pouvoir lire correctement un texte à l'écran, ou scanner un code QR par exemple. Dans ces cas, j'ai souvent constaté que quand je clique sur le bouton de l'extension pour ouvrir le menu, cette dernière plante / met beaucoup trop de temps à charger. Il est ainsi très pénible voire impossible de changer rapidement du thème sombre au thème normal.

Probably one of the most important if not greatest Add-ons Ever! My eyes no longer hurt at night. I totally recommend this to anyone who loves to view websites without the eye straining bright colors! This add-on truly made my browsing experience much more comfortable.

100%

Nicht so gut - schwarz bleibt schwarz, man kann teilweise nicht alles (Bilder, Texte,...) erkennen
