My email address is in use by another Firefox account user?

more options

I just tried to add a secondary email address to my Firefox account and get an error message stating that this email address is in use by another Firefox account user (already verified by another user).

Is there a way of finding out which account it is registered to? I can't recall ever using this email address in Firefox before?

Thanks

Hi Grant, please ignore the fake support link someone is spamming here.

Unfortunately for you (but fortunately from the perspective of someone's privacy), you can't find out about a Firefox Account just from the email address.

I don't think someone else could use the address unless they verified it, so is it possible you have another account?
