Changing browser for IPython Notebook from system default

Question

I would like to keep firefox as my system default browser on my Mac, but launch IPython Notebook in Chrome^[1].

This answer led me to my ipython_notebook

Answer 1

For people who want to make firefox their default for ipython notebooks (where it is not necessarily the system default), adding the following line to ipython_notebook_config.py should be sufficient:

c.NotebookApp.browser = 'Firefox'

For me, this was better than linking to the application file directly because it avoids the error: A copy of Firefox is already open. Only one copy of Firefox can be open at a time.
