Could someone help out? It looks like I lost my jupyter notebook while trying to work on the Python exercise in week two of this course. I am running the course on Chrome, but noticed that Firefox opens while working on the notebook. I deleted Firefox as I thought it was not needed. Now, when I try to access the my work it is not there. In fact, when I hit the “Work in Browser” button, it leads me to a page that says in bold print Page not Found.

Eeeek! It sounds like you must have also deleted the notebook file, while you were deleting FireFox. Fortunately there is a way to recover a clean notebook, but any work you have done previously is probably lost. Well, unless you accidentally renamed the notebook, instead of deleting it. Please have a look at this article, which is also linked from the DLS FAQ Thread (worth a look on general principles).
