This is all I have on Sync :

There is contact info in this and yes do have to create a account and wait : https://support.mozilla.org/en-US/kb/forum-response-firefox-sync-verification-email-faq

That is *SO* not helpful.

I've definitely noticed this problem. LastPass will notify you of duplicate logins, why doesn't FireFox? I'm never sure which login I used last time so I end up saving it to the wrong login, because it always asks me every time I login or change things. I feel this should be a feature. Firefox should make certain that the same account login isn't being duplicated inside Sync.

Hello Jayde,

Maybe you can explain more what you're trying to do. Your title asks about Sync, but your question seems to be about a Password Manager.
