Running program (firefox) instead of DE linux (debian, ubuntu)?

Question

linux

Hello, dear members of the TOSTER community!
There was a task to launch an Internet browser on a certain machine instead of a working environment, how can this be organized using ubutu, debian?
1. When the system starts, the user immediately sees the firefox browser window.
2. The user is not given the opportunity to minimize, move the browser window.
3. The user does not have access to the working environment (DE).
Thank you for your attention!
