Unfortunately this isn't a Firefox issue if the user fails to update to the correct new Primary email login. One should remove the secondary email first and verify the Primary is a working email to get the reset. At this point it's up to the user and their email provider to resolve this issue with the wrong email reset as Firefox is just a user forum and can't fix this since there is no steps to verify the owner of the Firefox account beyond the password reset sent to the Primary email login to update the change.

This is 100% a "Firefox issue". I didn't "fail to update to the 'correct' new primary [not a proper adjective, don't capitalize it] email". Step 3 is "Make email2 primary". Please read carefully before spamming replies.

this issue with the wrong email reset

There is no "issue" with the "wrong email reset". WTF are you even talking about? Read the post. Think it through. THEN make a thoughtful reply.

When switch email to primary it send reset to primary email previous and if you delete that email account from the email services then it will not reset since there is no confirmation of the change.

WTF are you talking about? "send reset to primary email previous" is nonsense.

"delete that email account from the email services" is equally nonsense.

Seriously, WTF are you talking about?

Do the steps, on a Firefox account. Do you expect all traces of email1 to be gone? What behavior do you expect, for a firefox account, after you've made email2 primary and deleted email1 from a firefox account? Specifically, when you enter email1 in a login flow, and when mozilla emails about the upcoming change from firefox to mozilla, what do you expect to happen? Because I've stated that I expect no trace of email1, because it's DELETED, yet, there it is, treated differently during login, and there it is, mozilla emails email1, the DELETED email, instead of the PRIMARY email, email2.

Listen here when you change primary email it send email reset to the prior email registered for the change. Does that ring a bell.

No. It doesn't "ring a bell". WTF is "email reset"? What is "prior email registered for the change"? Just follow the steps laid out in the OP. Answer the questions I've already asked you. What do you expect to happen WHEN YOU FOLLOW THE STEPS?

If you delete the email service account from the email online service then the reset to confirm the change will not happen nor can it receive to confirm the change.

WTF are you talking about? There's no such thing as an "email service account" and what the fkuc is "email online service"? Stop using insane nonsense. Just get clear and direct. Do the steps. Answer the questions about what you expect to happen AFTER you've followed the steps. You're in la-la land.

Your confusing email long with email account services two different services.

There's no such thing as "email long". There's no such thing as "email account services". WTF are you talking about? Just do the steps. Answer the questions. Don't say any crazy weird shit about nonsense, non-English word, not-things like "email long", "email account services", and "email service accounts".

Firefox uses email login for Firefox account and sync and your online email service is two separate services and one is required when password reset or changing to different email login before deleting that email account from the online email service if one wants to register a different email for Firefox account and notifications and sync.

Yes. Firefox account isn't the same as email account. I'm not claiming nor even insinuating that firefox account is the same as email account. You can add the word "address" to every instance of "email" in my OP to help you understand that I'm NOT conflating firefox account with email account.

Steps to reproduce: 1. Create a Firefox account with email ADDRESS 1. 2. Add a secondary email ADDRESS 2. 3. Make email ADDRESS 2 primary. 4. Delete email ADDRESS 1 FROM YOUR FIREFOX ACCOUNT. NOT the email ACCOUNT, the email ADDRESS.

Expected behavior: no trace of email ADDRESS 1.

Actual behavior: when you try to log on to firefox account with email ADDRESS 1, it remembers this, and says to enter the primary email ADDRESS to log in. a la https://support.mozilla.org/en-US/questions/1388872

When firefox emails me that firefox accounts are becoming mozilla accounts, they email the DELETED email ADDRESS 1! This is incredibly frustrating!

Does this specification help you understand?
