Firefox just displays the encoded URL

This is why it’s important to use bookmarks and never trust an unexpected link sent to you via e.g. email and don’t trust search results to be genuine. I once watched a family member search “Gmail” and click the first sponsored link. It sent them to “g.maìl.com” or something (I don’t remember the exact link) with a phishing lookalike login page. Many people search every time or trust a normal looking link instead of using bookmarks which is a huge risk unfortunately in 2026 with sponsored links and domain manipulation
