Environment: Device: Asus ZenPad (Android 6.0.1); Build: Nightly 53.0a1 (2017-01-08) Steps to reproduce: 1. Disconnect account and clear private data. 2. Go to Settings> Sign in. 3. Go to Forgot password and send a password reset email. 4. Open the link from the password reset email. 5. Fill in the new password. Sign in. 6. Go to Settings> Sign in menu again and check if the account is logged in. Expected results: The account should be logged in and sync should start. Actual results: The account appears to be signed in, but an error message appears under Sync "Cannot connect. Tap to sign in". Notes: - Reproducing on Nightly 53.0a1 (2017-01-08) & Aurora 52.0a2 (2017-01-09). - On Firefox 50.1.0 & Beta 51, the user is signed in and can sync the account immediately after password reset.
Too late for firefox 52, mass-wontfix.
