I created a firefox profile from another, so I start with the same saved passwords and bookmarks which is nice. Now I want to sync this new profile with the sync service of the mozilla account. First, I tried to use the same mozilla account I was using for the original profile (which would be ideal), but I get an error saying: ''This account is already in use''. OK, so I thought, instead, I could use an alternative mozilla account to sync this new copied profile, but, when I try to register/login with another account I get this other error: ''This profile was previously synced with a different account. To keep your data organized and secure, each Firefox profile can only be synced with one account. To log in using ***@***, you must create a new profile.'' Isn't there anyway to sync this new profile to a mozilla account? What's the whole point of copying profiles if you, after, cannot sync it? :/
