I'm running the latest Firefox v33.0.2 on Windows 8, but i've also tried the following on a laptop running Windows 8 and a Galaxy S5 running Android.

Problems started this morning when i re-installed a laptop running Windows 8 and installed Firefox v33.0.2. I went to setup Sync and couldn't sign in. All known passwords didn't work. I requested to reset the password.

I can't login to Sync, all known passwords dont work.

If i click forgotten password for my main account i get 'Unexpected error'

If i try and create a new Sync account and then Forgotten password as i can't login  :

I receive the forgotton password email, but almost immediately i get the error - Reset password link expired. The link you clicked to reset your password is expired.

If i click the 'Click here to receive a new reset link' i get the error 'Unknown account'

I can't sign up for a new Sync account - it says working, then an error occurred, although i do receive a verify email, but if i click on the link, created less than 2 minutes before it tells me 'Verification link expired The link you clicked to verify your email is expired.'

If i try and sign in, despite receiving a verification email it tells me the account doesn't exist!

So, i can't login to Sync, i can't reset my password and i can't sign up for a new Sync account - Every option simply doesn't work, so i'm assuming everyone must be experience Sync problems if they sign out and try to sign in or setup Sync on a new device?

What's going on with Sync, the whole system seems to be broken?

I've tried this on 3 different devices and get the same results!

Please help!

Hey there,


Apologies for this issue, sounds very irritating :/ It seems this is a fairly widespread issue, but as the vast majority of us are volunteers (including myself) we don't have any access whatsoever to the servers for security reasons. Therefore, I've flagged this up for a member of Mozilla staff or someone who can help you better to follow it up - they should get back to you soon.


Sorry for the inconvenience!

Ok to follow up and narrow down the issue can you please try the following:

  1. make a copy of the login file in your current profile folder. This is located

https://support.mozilla.org/en-US/kb/profiles-where-firefox-stores-user-d... in these files: key3.db and logins.json

  1. Grab these and paste them into a new profile and add this to the new profile to eliminate if this is an issue with the password file.
  2. Profile Manager - Create, remove, or switch Firefox profiles

If the passwords work in the new profile the logs would be helpful to investigate further.

  • How do I turn on sync logs:
  1. Open about:config and turn on: services.sync.log.appender.file.logOnSuccess and services.sync.log.logger.engine.bookmarks
  2. Restart Firefox and look at: about:sync-log
  3. Logs and error messages will be located here

Please also use pastebin.mozilla.org for sharring any errors that relate to this issue.

Thank you.
