Dark reader is great. It can also be used to prevent fingerprinting based on your preference, as most are configured to light mode by default.
However it often makes the site nearly or completely unusable, as it isn't (and can't) always be 100% correct. Having dark mode configured by the site is often much more useful.
or... just lower your monitor brightness so you don't feel like you need dark mode, which is actually worse in every way than just using the correct monitor brightness.
Sorry I didn't mean any negatively towards you there. I just remember what the site was like before it hit my blocklist. It was before chatgpt got big but everything I read on there was scraped info from other sites and full of errors
Firefox with the extension "Dark Reader" is great. There are some websites I have to disable it, but it's rare. I also recommend uBlock Origin.
Edit: I see someone already recommended dark reader. But it really is a must have extension. It knows if your system theme is set to light or dark and matches it automatically.
