I went through documentation on GitHub for Sync Protocol as well as other similar questions. I got basic understanding of how Sync security works. But still I would like experts to confirm this.

1. Master password is only used to encrypt data on local computer. 2. Sync account password is used for encrypting data before sending it to Mozilla servers. 3. Data on Mozilla servers is meaning less unless you know the Sync account password. 4. Mozilla does not store Sync account password anywhere. But instead they use hash/digest comparison method(or a similar method) to make sure that entered password is correct.

Could anyone please confirm above points?

One additional related question I have is, 1. Even if I do not set master password, I see that data is logins.json is encrypted. How this encryption is achieved?

Thanks Seburo.

I went through article. It does not mention how logins.json data is encrypted when master password is not set. But anyway, it is appropriate/wise to assume that when master password is not set all your passwords are in plain text.

Thanks Seburo and Mozilla.

The point is if a master password is not set anyone with access to your Firefox may obtain the logins as simply as you can. Plus anyone with access to the computer and Firefox profile also has all those logins available.

I suspect the encryption of the logins within Firefox even when a Master Password is in use not very secure but unfortunately I do not recall where I saw that mentioned. (Probably in relation to Sync & Master password bugs) If you wish to obtain further information try the Mozilla forums, and if you do post there maybe let us have the link so we may follow the post
