Introduce master password for already synced computers?

I have 3 computers (1 Mac, 2 Ubuntu) synced via Firefox Sync. Currently my passwords are unprotected.

Now I would like to introduce a master password on all of my computers. But somehow, if I set up the master password on one computer, my passwords are still unprotected on the other computers. Even when I completely delete all data and re-sync, I can access my passwords without master password on the other computers.

How do I have to proceed in order to get the passwords on all computers protected with a master password while still being synced, and at the same time make sure that there are no remnants of unprotected passwords on any computer or the firefox server?

Alternatively, if I stop syncing passwords on all devices, will they be deleted from the sync server?

hi xaggi, we have to differentiate here - a master password is protecting passwords locally on a device. strong encryption is already built-into sync, so you need no extra measures to protect the passwords on the sync servers except than choosing a strong account password in the first place (technical details at https://github.com/mozilla/fxa-auth-server/wiki/onepw-protocol - your data gets encrypted locally before it is submitted to the sync servers, with no way of accessing that data for third parties like mozilla without knowing your credentials).

if you want to use master passwords on your other devices as well, you can do that but have to set them up manually - this isn't a setting that gets transferred through sync...
