I hate dark mode, it seems there is always enough non "compatible" stuff to blind you. Like sometimes dark mode works, except for the parameters page that burns your eyes out without a warning. Or 1 soft in dark, the other in white, ir darkmode but the surroubding panels arr light?
I've been using "dark mode" since the early 2010s. When the concept gained a measure of acceptance, there were many edge cases. Nowadays, almost every app has dark mode in-built and extensions allow easy, transparent dark mode for almost all websites.
I use Darkreader as well, haven't really felt the need for using anything else. It's simple but very powerful (and with very few exceptions and errors in my experience).
