I really liked Dark Reader at first but over time I ran into too many edge cases and bad themes across the web where I felt like the time tweaking sites wasn't worth the effort any more. I had to turn it off for so many sites I eventually uninstalled it. Now I'll only use dark mode if the site natively supports it (more and more are lately), otherwise I'm not crazy about playing cat mouse game hacking dark mode into sites that don't support it.
Dark Reader has 4 different themes. The default one does the job maybe 80% of the time, but whenever I encounter a site that looks a little wonky, I just click through the other 3 themes and one of them usually works much better. Then, I save that as the default theme for the site.
