Passwords for Firefox Sync are not correctly stored

[YukiChiba]

I get a message every time I start FIrefox on the window bottom, saying "Sync encountered an error while synchronising: Incorrect account name or password. Sync will automatically retry this action.".
Then, If I try to sign in again, I have to enter masster password to use saved password, but it fails.

Without this extension, no error occurs.

I compare stored passwords with this extension via seahoce and without it via Firefox Preference:

• With this extension
  • Description: chrome://FirefoxAccounts
  • Use: Saved password or login
  • Type: Password
  • Password: {"version":1,"accountData": "sessionTokenContext":"fx_desktop_v1","unwrapBKey":"#####","keyFetchToken":"#####","customizeSync":false}}
  • Details:
    • passwordField:
    • formSubmitURL:
    • hostname: chrome://FirefoxAccounts
    • usernameField:
    • httpRealm: Firefox Accounts credentials
    • username: (my username)
    • mozLoginInfoMagic: loginInfoMagicv1
• Without this extension
  • Site: chrome://FirefoxAccounts (Firefox Accounts credentials)
  • Username: (my username)
  • Password: {"version":1,"accountData":{"sessionTokenContext":"fx_desktop_v1","customizeSync":false,"kA":"#####","kB":"#####"}}

Here, "#####" denotes strings consist of random alphabets and numbers.

I love this extension and I'm very glad if it is supported to store passwords for Firefox Sync.

I have the same issue. Firefox Sync breaks with "Sync encountered an error while synchronizing: Incorrect account name or password. Sync will automatically retry this action." after each restart.

Sync works well with addon uninstallled.

Beside that, I am very happy with this addon.

Same here. It worked fine for me before upgrading to Firefox 38.0

Same here with Fedora 23 and Firefox 41.0.2.
