This worked really well for some websites and didn't work on others. There were some issues on some websites where it worked too - for instance if you open a video on youtube it was able to convert it to dark mode, but it wasn't able to change the font color of the channel to a different color which made it practically invisible as black on black.

Addon is perfect but with dynamic theme i have slow page load on youtube and blog with vbulletin. The others themes dont work correctly. For example in yt when i have change to filter or filter+ the left bar words, dissipated. In all other sites i have not problem. Please make something about dynamic theme.

This addons/extension is very good for my eyes because makes the websites dark so my eyes is not hurted anymore.

It works. And it often makes websites look better than the official dark theme. Easy to switch off on a per-website basis when something is obscured. The UI for that isn't obvious though (you have to click the website name in the Dark Reader box).
