I have had random freezing on the mobile Firefox for months now. I typically search in a private tab with a bunch of trackers disabled. If I do the same search in Chrome, Edge, Samsung Internet (in their incognito tabs) the searches load. This seems like a block on Firefox itself

Bingo

I am! I think this is intentional on both Apple and Google to force you to use their apps

It makes the choices look strange though. You see the Google suggestions and the Apple suggestions even though those aren’t the default. This is that walled garden in action on both Apple and Google’s side.
