Sign in address has changed since first sign in years ago
My address has changed since original Firefox sign in. You asked for main email which I used . It’s ok but different from original. Can I have the one on my computer which is old and the new one for Firefox on my phone?

If your using one Account they have to be the same email login. Only difference if you have two different Mozilla accounts then they will be different logins. But you should use different account so any data from the two accounts don't merge with the other data on the same browser.
Assuming you want one account for all your devices, assuming you still have access to the primary account, do you want to switch the addresses? Please see the following article for more information:
