Setting the Default Browser for JupyterLab on Linux

To change the default browser for JupyterLab on Linux, follow these steps:

1. Open a terminal and run the following command to generate a configuration file for JupyterLab:

   jupyter-lab --generate-config
   

   This will create a jupyter_lab_config.py file in $HOME/.jupyter.

2. Open this file in your preferred text editor.

3. Find the line:

   #c.ServerApp.browser = ''
   

   Remove the # to uncomment it.

4. Replace the empty string '' with the path to your desired browser. For instance, if you want to use Microsoft Edge, update the line to:

   c.ServerApp.browser = '/opt/microsoft/msedge/msedge %s'
   

5. Save the changes.

Now, when you launch JupyterLab, it should open in your chosen browser by default.
