I want to create a new user who has the ability to access internet and put any of their downloaded files to his/her pen drive. That's it. He/she should not be able to install any new software. Should not be able to navigate to any other folder other than their home folder. Should have the access to Firefox only to access Internet.
Is it possible to do this in Ubuntu? If so, please guide me in how to do it?
I want to create this sort of a user account, so when a friend/relative of mine wants to use my laptop to access Internet for browsing, and downloading any files they need, I want to give them access to this account.
