You could just create a new user called "guest" once, and lock down your home folder so other users can't see your files? Then log out or lock screen and switch user, for somebody else to use your computer. The feature then lacking being that if one guest saves a Firefox bookmark, for example, that would be visible to the next guest also.
To lock your home folder so only you can access your files, open a terminal and do:
- Code: Select all
chmod 700 ~
This will change the permissions on your home folder so that only you can look into it (and root, obviously, so don't hand over your root password
Not a perfect solution, but a workaround for now?
