MpdJupyROOT does not start webbrowser automatically

EDIT 2023-12-11: SOLUTION

toolbox enter a9-nica-dev
wget -N https://git.jinr.ru/nica/nicadist/-/raw/master/scripts/jupyter-fix.sh
chmod +x jupyter-fix.sh && ./jupyter-fix.sh

and the firefox should auto open in parent OS when running mpdJupyROOT.
Closing this

EDIT 2023-12-08: dirty working hack , after

toolbox enter a9-nica-dev
sudo nano /usr/share/applications/code.desktop

edit lines that start with Exec to look like this

FIX
container a9-nica-dev must contain file

/usr/share/applications/firefox.desktop  

in which Exec lines must look like in the above hack,
this file must be set up as default one to handle webfiles by

xdg-settings set default-web-browser firefox.desktop
