Fórum da Comunidade de Firefox para o Android

I have a Mozilla Firefox login with hundreds of bookmarks, I've been saving for years. With the recent update, I was logged out. I tried to log back in with my saved password and email. The information I have is correct. The problem lies in the fact that I created that login & pass with a University email. After graduating,the ending of the email address was changed to @alumni.edu sort of thing. So now it's trying to send me a security code to login and I cannot receive it because of this change to the email address, thus I cannot get logged back into my firefox to retrieve my bookmarks. Please help.

I no longer have the primary email account I registered with Firefox (It was a paid for private domain that I discontinued a few years back). how do I make my second email address on file the primary?
