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.
