[SOLVED] The Minimize button on Firefox Gnome desktop

Hello,

I'm trying to get a minimize button to the firefox window and i receive this message:

root@debianalain:~# gnome-tweaks -l
Unable to init server: Could not connect: Connection refused
Unable to init server: Impossible de se connecter*: Connection refused
Unable to init server: Impossible de se connecter*: Connection refused

(gnome-tweaks:6647): Gtk-WARNING **: 03:01:08.939: cannot open display:
root@debianalain:~#

What does that mean and what can i do ? :(

Thanks for your answer (i'm a new user of debian 10 buster, Gnome desktop)

Alain

PS: Found answer: Hold Win Key and right clicking on the title bar gives a new menu with a minimize option :)latest?d=yIl2AUoC8zA latest?i=CCCHp-ayRU4:fnWgobNQHkE:F7zBnMy latest?i=CCCHp-ayRU4:fnWgobNQHkE:V_sGLiP latest?d=qj6IDK7rITs latest?i=CCCHp-ayRU4:fnWgobNQHkE:gIN9vFwCCCHp-ayRU4
