usually I love to shit on muricans, But Germany has something similar. A private company called "Schufa". This private company secretly calculates your credit score (no one knows realy how they calculate it) which determines if you get an apartment (for rent) or not. Living in the wrong street already kills your credit score here.
If the Schufa doesnt have information about you, it counts as negative.
The same DNS settings work in Opera GX, which means the problem is made by Mozilla
I tried switching to Firefox some weeks ago but deinstalled it immediately after realising that it's DNS doesn't work. My ISP is censoring some 🏴☠️ websites and I can only visit them by not using my ISP's dns service.
No matter which DNS i selected in the browser settings I always got an error saying that Firefox couldn't reach the DNS. I will stick to Opera GX now 🤷♂️
Edit: it's funny how the butthurt Firefox users downvote me for just talking about my experience with the browser.
Let me guess, you are a murican?
