I changed my email ages ago, But when i try to log in with linux or firefox portable it doesn't work

more options

I changed my email address in firefox settings a while ago, had no problems since. But recently wanted to use firefox portable. What happens is, i log in with my (new) email, I get sent an authentication code to the new email, i type it in, then it tries to login with my old email and obviously fails (Incorrect password)

I've also tried using a linux laptop, and i can't login with it either, but it works fine on android and windows. If i try it too many times my account locks, don't know what to do
