I use Firefox 150.0 on a MacBook Pro, and a couple of days ago, the large Swedish news website dn.se (Dagens Nyheter) started behaving strangely. The site now displays only one column, which covers the entire screen, hiding the sidebar and ads.
Interestingly, the site displays correctly in Chrome, Safari, and other browsers. Even Firefox on iOS renders it properly (though adapted for mobile).
Do you have any ideas about what might be causing this issue?
