Hi do.infinity,

We are working on a solution that gives a notification when the email bounces back for signing into sync. You currently cannot edit the email in your sync profile if you are logged in. An alternative is to back up the current profile and to create a new account with a working email.

However, if the email is correct and you still get a bounce back email notification, I might recommend creating a new sync account with a working email if all of the current history, passwords, and other profile data are stored on your current device/computer. Just remove the account in the profile and create a new one.

Please feel free to PM me directly if the domain name of the email is not a common one and we can open up a private bug with your email, however I cannot guarantee a solution.

my email is correct - been using it for decades - are you saying i have to get a new email?

roadplug, no, that is not what I am suggesting. There is a process where we can open up a new bug in bugzilla.mozilla.org with eh accounts team to investigate any unexpected optimization in the Firefox Sync profile.
