Chrome's user interface is much more beautiful than Firefox's. I suggest you redesign Firefox's user interface.You had to mimic Chrome's user interface when designing Firefox's new user interface.When installing Firefox for the first time, let the user choose to use a user interface, one for the classic user interface, which is now the user interface, and the other for the Chrome-like user interface.
Some users use Chrome instead of Firefox because Chrome has a cleaner and more beautiful user interface than Firefox
