メモ。
jupyter notebook を使う時に、フォント設定からやり直さないとフォントを変更できないブラウザがデフォルトになっている場合など、使っていないブラウザのことを調べないといけなくなるので、設定済みのブラウザで開きたい。
具体的には windows で microsoft Edge で開いてしまう jupyter notebook を chrome で開いて、フォントのレンダリングを慣れた見た目にしたいという用途で、jupyter notebook の起動で呼び出すデフォルトのブラウザを変更する。
jupyter_application_config.py を書き出して、vim などのエディタで以下を追記する。
jupyter_application_config.py
import webbrowser
webbrowser.register('chrome', None, webbrowser.GenericBrowser('C:\\Program Files (x86)\\Google\\Chrome\\Application\\chrome.exe'))
c.NotebookApp.browser = 'chrome'
jupyter_application_config.py を書き出すまでの手順としては、
Jupyter notebook をコマンドプロンプトで起動。
jupyter notebook
ブラウザの中の Terminal を起動して
jupyter notebook --generate-config
もしくは、コマンドプロンプトで上のコマンドを実行しても同じだと思われる。
その後、jupyter_application_config.pyを探して、目的のブラウザのプログラム本体のパス、インストールされている場所（.exe が存在するパス）をきちんと調べて、jupyter_application_config.pyをエディタで開いて、編集する。
一番最後に追記するとこうなる。

# The string should be of the form type:salt:hashed-password.
# Default: ''
# c.NotebookApp.password = ''
## Forces users to use a password for the Notebook server. This is useful in a
# multi user environment, for instance when everybody in the LAN can access each

#
# In such a case, serving the notebook server on localhost is not secure since

# c.NotebookApp.show_config_json = False
## Shut down the server after N seconds with no kernels or terminals running and
# no activity. This can be used together with culling idle kernels
# (MappingKernelManager.cull_idle_timeout) to shutdown the notebook server when
# it's not in use. This is not precisely timed: it may shut down up to a minute

# details.
# Default: {}

## Supply overrides for terminado. Currently only supports "shell_command". On

# default when the notebook server is connected to a terminal, a login shell
# otherwise.
# Default: {}
# c.NotebookApp.terminado_settings = {}
## Set to False to disable terminals.
#
# This does *not* make the notebook server more secure by itself. Anything the
# user can in a terminal, they can also do in a notebook.
#
# Terminals may also be automatically disabled if the terminado package is not
# available.
# Default: True
# c.NotebookApp.terminals_enabled = True
## Token used for authenticating first-time connections to the server.
#
# The token can be read from the file referenced by JUPYTER_TOKEN_FILE or set
# directly with the JUPYTER_TOKEN environment variable.
#
# When no password is enabled, the default is to generate a new, random token.

## Supply overrides for the tornado.web.Application that the Jupyter notebook
# uses.
# Default: {}

# SSL
# Default: False
# c.NotebookApp.trust_xheaders = False
## Disable launching browser by redirect file
#
# For versions of notebook > 5.7.2, a security feature measure was added that
# prevented the authentication token used to launch the browser from being
# visible. This feature makes it difficult for other users on a multi-user
# system from running code in your Jupyter session as you.
#
# However, some environments (like Windows Subsystem for Linux (WSL) and
# Chromebooks), launching a browser using a redirect file can lead the browser
# failing to load. This is because of the difference in file structures/paths
# between the runtime and the browser.
#
# Disabling this setting to False will disable this behavior, allowing the
# browser to launch by using a URL and visible token (as before).
# Default: True
# c.NotebookApp.use_redirect_file = True
## DEPRECATED, use tornado_settings
# Default: {}
# c.NotebookApp.webapp_settings = {}
## Specify Where to open the notebook on startup. This is the `new` argument
# passed to the standard library method `webbrowser.open`. The behaviour is not
# guaranteed, but depends on browser support. Valid values are:
#
# - 2 opens a new tab,
# - 1 opens a new window,
# - 0 opens in an existing window.
#
# See the `webbrowser.open` documentation for details.
# Default: 2
# c.NotebookApp.webbrowser_open_new = 2
## Set the tornado compression options for websocket connections.
#
# This value will be returned from
# :meth:`WebSocketHandler.get_compression_options`. None (default) will disable

# Default: None
# c.NotebookApp.websocket_compression_options = None

# Session(Configurable) configuration
#------------------------------------------------------------------------------
## Object for handling serialization and sending of messages.
#
# The Session object handles building messages and sending them with ZMQ sockets
# or ZMQStream objects. Objects can communicate with each other over the
# network via Session objects, and only need to work with the dict-based IPython
# message spec. The Session will handle serialization/deserialization, security,
# and metadata.
#
# Sessions support configurable serialization via packer/unpacker traits, and
# signing with HMAC digests via the key/keyfile traits.
#
# Parameters ----------
#
# debug : bool
# whether to trigger extra debugging statements
# packer/unpacker : str : 'json', 'pickle' or import_string
# importstrings for methods to serialize message parts. If just
# 'json' or 'pickle', predefined JSON and pickle packers will be used.
# Otherwise, the entire importstring must be used.
#
# The functions must accept at least valid JSON input, and output *bytes*.
#
# For example, to use msgpack:
# packer = 'msgpack.packb', unpacker='msgpack.unpackb'
# pack/unpack : callables
# You can also set the pack/unpack callables for serialization directly.
# session : bytes
# the ID of this Session object. The default is to generate a new UUID.
# username : unicode
# username added to message headers. The default is to ask the OS.
# key : bytes
# The key used to initialize an HMAC signature. If unset, messages
# will not be signed or checked.
# keyfile : filepath
# The file containing a key. If this is set, `key` will be initialized
# to the contents of the file.
## Threshold (in bytes) beyond which an object's buffer should be extracted to
# avoid pickling.
# Default: 1024
# c.Session.buffer_threshold = 1024
## Whether to check PID to protect against calls after fork.
#
# This check can be disabled if fork-safety is handled elsewhere.
# Default: True
# c.Session.check_pid = True

## execution key, for signing messages.
# Default: b''
# c.Session.key = b''
## path to file containing execution key.
