I've never made any password on my computer, besides the one to get into the user account. I tried that password for this and that didn't work. I don't think I've even heard of a master password. I have no internet till I put a password in. Please help!!

This happens when you have activated FIPS mode via the button in the Security Device Manager.

The only way to recover from this is to delete the key3.db file and the logins.json file in the Firefox profile folder. You will lose all stored passwords doing that.

You can use this button to go to the currently used Firefox profile folder:
