Ratings and reviews

It's otherwise a good browser, but if they could *please* let us put the navbar functions back in the overflow menu, I would appreciate it. Might just be me, but I do not like having UI elements unceremoniously relocated to other parts of my display, especially when it's without prior notification or consent. Even if it's just a customization toggle, it would be nice, as I don't want to have to switch back to normal Firefox to remove it and lose access to my custom extensions list.

The changes as of two days ago make the browser unusable. The URI is no longer displayed in the address bar - now it's just the domain, which makes verification impossible. There's a new 'navbar', pinned to the bottom, which messes up all the accessibility flows. I have no idea what the UI/UX people were thinking, but they need to rethink and revert immediately.

I hate forced layout changes, please make them optional. I don't want bars on the bottom, it messes with muscle-memory functions, which makes browsing slower. Going forward, I would prefer features like this to be optional with the rest of the ui in the settings or about;config. That's why we have the "address bar location" option in first place. Al least let people know what features will be added ahead of time, so we can skip the update, instead of having to roll back a version.
