How do I suggest improvements on the iOS app? The address bar needs fixing.

I absolutely love Firefox on PC so thought I’d try it on iOS and while I really want to move from Safari to Firefox so I can sync across devices, I simply can’t move to iOS Firefox when the address bar wastes so much screen space. It’s an eyesore and incredibly distracting for seemingly no reason as there’s a lot of empty space; it could easily be half the size. If you guys could offer different address bar designs that would be amazing because something similar to the small address bar in iOS Safari would be great. It’s very rare I criticise anything to do with Firefox but sorry, it needed addressing (pardon the pun).
