When my computer is open my son can access the internet through Firefox. I want to prevent this by adding a password whenever trying to log in to the internet. How do I set this up?

Thank you,

Eric

The master password is only used to encrypt passwords saved in the password manager and doesn't prevent from opening Firefox.
You can't prevent that.
There are extensions that allow to open a profile only after a password has been entered, but extensions can easily be bypassed if you know how to do that e.g. by holding down the Shift key.
