Hello mplatner, First of all : it might be wise if you'd remove your email address - this is a public forum and anybody could start sending you spam .... About your problem : If this is about a Firefox Sync account, I'm afraid that you will have to create a new account, with the correct email address. Please see : https://support.mozilla.org/en-US/kb/ive-lost-my-firefox-sync-account-information (you'll have to scroll down some)
