Don't see that option to disable, it just says enable like in your screenshot.

Every time I come to this website I'm forced to log in and deal with an email sent to my email account containing a 6 digit code, did not have to go through all these extra steps when I didn't have to use a firefox account to get answers to those really ugly bugs that show up.

I think this is the most relevant article, What if I'm locked out of Two-Step Authentication?

This doesn't sound like a 2FA issue as you indicate you have the button to enable 2FA.

Are you using the Firefox Password Manager (Lockwise) ?

Firefox would normally store the credentials for the Firefox Account as a hidden entry in the Password Manager and use these to login automatically (you may have to enter the master password or Windows PIN/Password).
If you lose this entry in logins.json then you will have to authenticate each time you start Firefox and need to login.
