Hi!
I don’t need this nonsense. I read that its automatically enabled for extension developers, which I’m not.
The only thing I ever done other than rate and comment is sign some extensions so I could use them in Firefox when it became a requirement years ago. Those were never addons that were published. So why am I harassed with this?
as you state you did sign some addons in the past, and if you’re signing any addons in AMO means you’re part of the Dev community as per se, because those addons based on tnc are addons that will be published by another channel/website that’s not AMO, and even you’re not publishing it, you already did sign. You need to see the FAQ of AMO for disabling 2FA
I disable 2FA via https://accounts.firefox.com/settings , There’re sub section named Security and there is 2FA, but you need to turn on 2FA first then deactivate it.
