title: Jupyter Notebooks Not Opening in Web Browser
body: <p>I am running jupyter-notebook : 6.3.0. In terminal upon running <code>jupyter notebook</code> I get directed to Jupyter labs in my browser. The folder directory (http://localhost:8888/tree) displays all files, however individual files do not open and I receive a loading, and then the page 'dies'. In Chrome, this is the 'Aw Snap' message with error code 5. Any idea what is going on here?</p>
