Ways to handle Thorium on public workstations

[gautierchomel]

If Thorium is installed on public and shared workstations, how secure access can be handled when multiple users access the same terminal? If one user logs in a catalog, downloads ebooks, reads and annotate them in Thorium, the next user will be able to view and access the previous user's logged catalog, downloaded files, including reading locations and annotations.

What are the ways to limite those risks? Shall we provide guidance? Do we miss any functionality for this use case?
