Hi   !
You can check on the about:sync-log page if there is a Sync error log available. You might have to turn on logs in order to capture any errors there. How to turn on sync logs : Type in the address bar about:config (promise to be careful, if asked) services.sync.log.appender.file.logOnSuccess and : services.sync.log.logger.engine.bookmarks

Then Restart Firefox and look at : about:sync-log Logs and error messages will be located there.

Note that you should reset services.sync.log.appender.file.logOnSuccess to false after you are done testing. Otherwise you will get a lot of logs getting saved because normally only when an error occurs a log is created.

Can you post the content of the error log?

You can upload a recent log if the log is too big to put in a reply.

Did you replace any files from that failing drive or did you create a new profile folder? There seems to be a problem with the Firefox account authentication data:

  • Status.login: success.login => error.login.reason.no_username

This could be a problem with the data stored in the Password Manager or other data stored in the profile folder or the weave folder (Sync was formerly named Weave).


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.

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.
