Dark Reader is a fine extension that works like charm but then if it is so why 1 star. Reasons?
On a lot of sites, it works like it is killing the browser and browsing experience and most of the time, browsers dies and we have to start again by disabling or stopping the extension thus losing data. Tabs behave like they have been brought under a lot of pressure and they cannot handle it anymore.
Plus, the settings look great but not that appealing. If I have set certain settings on a certain web link and different on another, it doesn't remember when we are browsing again in a new session another time.
Also, my suggestions are also for adding modes for reading, viewing, watching, eye straining or more which dev can learn from other such apps or softwares.
Plus, I have some doubts about privacy and whether or not, this extension overshadows and records via facility it provides what we are doing when extension is enabled,
I hope dev will understand and see the link which i have provided to understand why i support this extension and will overcome these issues as soon as possible.
Also create an android and ios and windows app.
