I don't know what Im did but I broke xfce4

Probably it broken after updates: I cant’ close Chrome for example – it hasn’t buttons under menu for this; in Firefox doesn’t work context menu (mouse left click on window) it disappears after move mouse on it, I can’t close terminal – haven’t buttons for this, and many others errors.
I was try to remove ~/.configs/xfce4 and /etc/xdg/xfce4/ – doesn’t helps
It helps one time (with remove ~/.configs/xfce4), but then it came back to broken state…

very imprecise
there is no:

only:
~/.config/xfce4

Do you want instructions on how to “return” to defaults?

/etc/skel/… holds them
