Saving usernames but not passwords
I would like Firefox to save my usernames for sites, but not the passwords. However, Firefox insists that I supply a password before it will save the account details, and if I supply a dummy password, then it will not let me later edit the account and delete the password. I like to remember my own passwords rather than store them anywhere.
I have tried password managers and they are overbearingly controlling, particularly given that they don't store my passwords let alone my 2FA details, so I'd rather just use Firefox's less onerous, built-in system, if only it would allow me to save an account without a password. Surely saving a username without a password is a safe option, so why block it?

Yes, the password is mandatory, the username isn't as this is a Password Manager. You need a form fill extension that stores its data encrypted to save only the username.
You should be able to edit a fake (one letter) password in the Password Manager.
