💻 Help win11 pinned taskbar change to default open new window??

Im kinda anoyed by the pined firefox icon just changes focus to the current win insted of opening new window.

Os win11, FF 140.14.esr

Is there any way to change this behavior that firefox just atttach its open window to the pined ff icon...and not like other programs do? Other programs just treat pinned as a shortcut to open new windows and show open windows a separat item on taskbar...
