Get rid of the new navigation toolbar or let us turn it off, at least when the address bar is set to the top. I want top navigation ONLY, not this absolutely awful split top+bottom combination. I switched away from other browsers to avoid this exact kind of awful UI, I don't want to have to switch away from Firefox as well to avoid it. Also why did you make the address bar smaller? There's no reason to have wasted space on the sides.

I love this app in spite of some of the experimental changes. The controls on the bottom separate from search placement grew on me. Either way is fine with me. I think there may be an issue with the way Firefox interacts with the phone's native "back" ◀ functionality. It's skipping a step. I noticed on YouTube's search.

It's been a good app for the time I've been using it, but then the navigation bar was sent to the bottom, which really threw me off. Not only that, you aren't allowed to change it back. I'd at least like the option to change it back because otherwise, I'm just going to be using an older version of the app. Still tedious though, because it automatically updates without my greenlight. Ticking me off here.
