One of my computers crashed and I am re-installing Firefox. When I attempt to sync the data, I have to respond to an email that is sent to my primary address, but I no longer have access to that email. When it changed, I tried to change my primary, but was told that is not possible. The work around was to put my new email as the secondary, which I did. But now the secondary address is vacant. If I try to add a secondary with my new address, I can't because it says that address already exists. Can anyone advise?
