by:
jupyter notebook --generate-config
Then you go to
~/.jupyter/jupyter_notebook_config.py
and change
# c.NotebookApp.browser=""
to for example:
c.NotebookApp.browser="/usr/bin/google-chrome %s"
You can choose which ever browser is installed. You’ll find the path for example by typing which firefox
Do not forget to delete the #
