I have Firefox for Android beta v39 and Firefox for Android v38 installed on my phone (Lollipop 5.0.2) and no matter which one of these browsers I try, when i login for sync, it gives the message "could not log in".. I have v38 installed on my linux desktop and it works with the same credentials. I tried resetting the password also and that also doesn't help, as the problem still remains the same.. sync on desktop works and it doesn't work on Android. Any suggestions?

I understand that Firefox for Android returns: "could not sign in" I am happy to help. Let's try a new login by removing the account first.

  1. First disconnect the account from the Android Settings under "Accounts"
  2. After tapping remove, open a new window in Firefox
  3. Go to https://accounts.firefox.com
  4. Sign in once more and make sure that in your Account Settings, that Data Usage is set to auto sync.

For troubleshooting, do you have any content blockers or proxies/filters on your device?
