Comment form for an article on mobile is not displaying correctly

Hi,
Posted the same request a year ago for another website and the situation is the same.

1. A way to remove the large 0 if there is no comment
2. How to place labels correctly or use placeholders
3. The information phrase for the registration is not fully displayed.
4. Still on mobile, if you submit an empty comment in Chrome or Opera, field completion alerts appear, but nothing appears in Firefox.

Thanks for your attention.

Rolland
