Sync doesn't fetch passwords from the server even though they exist there

Today I realized I only have 2 stored passwords locally, whereas I had dozens before. I checked Sync and it was disconnected. I reconnected it, but the passwords didn't arrive.

I installed the "About Sync" plugin to check the server data, and indeed the server has all my passwords, but the plugin reports (rightly) that the client is missing them. Yet, they don't get synced, even after manually click "Sync now"

I opened my Sync account (https://accounts.firefox.com/settings/clients?service=sync) and there is a duplicate of my current machine there. However, I don't feel comfortable with deleting the duplicate, as it might be perceived to be the one storing the missing passwords and deleting it might result in them being lost forever. The whole think looks like a bug, so I'm stepping lightly.

I renamed the current machine in the accounts.firefox.com/settings, tried syncing again, didn't work.

Here's the latest log file from the about sync plugin:

Looks like login is failing, even though firefox reports that I'm successfully logged in.

In case of issues with Sync you can try this: Disconnect from Sync and Reconnect to Sync again. You can disconnect from Sync by clicking the e-mail address in the "3-bar" Firefox menu button drop-down list or go to "Options/Preferences > Sync". Delete the signedInUser.json file in the Firefox profile folder and delete the Weave folder (Sync was formerly named Weave). Remove an existing chrome://FirefoxAccounts entry in the Firefox Password Manager. If that isn't enough then delete the prefs.js files to reset all prefs and maybe also delete the compatibility.ini file to reinitialize the profile.

You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.

Thanks. Deleting the signedInUser fixed the problem. Two comments: - I have a firefox profile folder in both AppData/Local and AppData/Roaming - the active one is Roaming, but I first checked in Local

- the signedInUser.json contained "null" - if that helps resolve future problems

Firefox uses two locations for the Firefox profile folder. Location used for the main profile in "AppData\Roaming" that keeps your personal data.

  • C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Profiles\<profile>\

Location used for the disk cache and other temporary files in "AppData\Local".

  • C:\Users\<user>\AppData\Local\Mozilla\Firefox\Profiles\<profile>\

In most cases you need the "AppData\Roaming" location since there is where your personal data is stored.
