  Have you tried to delete the signedInUser.json file in the Firefox profile folder?

  Con - El,
  Thank you. Yes, I've always seen the Firefox Sync credentials, and I can't connect to accounts.firefox.com/settings.

  This morning, I deleted the signedInUser.json file in the profile folder, rebooted Foxfire and signed in Web sites. I left the PC to go to sleep. Wake up two hours later, there is no error message.

  I note that the file signInUser not re-emerged during the re-start of Firefox. If at this point, it looks like to solve.

  Thank you

• Whenever I run firefox I get "Sync has encountered an error during synchronization: Incorrect account name or password." Sync automatically retrying this action. "

  I am using the new firefox Sync since it is has been implemented without problem. I got this error after you perform the following steps:

  (1) old drive replaced with the new SSD drive and installed Windows 7 drivers etc + Firefox
  (2) deleted AAA@***.com Firefox Sync account
  (3) BBB@***.com Firefox Sync account created
  (4) imported my favorites last folder E:\Users\***\AppData\Roaming\Mozilla\Firefox\Profiles\***.default\bookmarkbackups on the old drive.

  Since then, whenever I open Firefox I get the above error. If I enter the password 'Firefox Sync' sync works fine until the next time that I restart Firefox.

  I think I've tried all the solutions on the firefox support forums and Firefox Sync troubleshooting.
  Among others, I have:

  (1) updating Firefox is
  (2) signedInUser.json deleted, restarted firefox with Add-ons disabled, account forget Firefox Sync, reconnect to the account
  (3) deleted Firefox Sync account and recreated
  (4) completely uninstalled with Revo Uninstaller, file C:\Users\***\AppData\Roaming\Mozilla\ deleted, reinstalled firefox firefox.

  Thanks for any help

  Thank you 1 million.

  You pointed me to the right direction. Manager of password has been activated, but it seems that firefox has reset my privacy settings.

  All I had to do was my privacy settingsand in my history of custom parameters, click parameters next to "Clear history of Firefox closing" and uncheck the box "Saved passwords" as in the following image

• Problem with sync error: synchronization has encountered an error during synchronization: unknown error. Sync automatically retrying this action.

  Hi, I started recently a problem with the sync on my desk. My partner Android and Mac laptop no problems when you attempt to synchronize, but office always gives the same error. I tried to disconnect from the desktop computer, erase all files, restart and then adding the Office to synchronize once more, but the error persists.

  All bookmarks on the desktop disappeared, but are still in my sync data and have no problem being viewed on other connected devices. It also tells me that the issue is not the sync server and that there is something unique to the desktop machine.

  I hope that this will not require a reinstall, but if all else fails, it's an option. I'll try to attach a log file once I put the question.

  I think the error message is in the title of the thread:
  
  Sync has encountered an error during synchronization: unknown error. Sync automatically retrying this action.

  Try creating a new profile as a test to check whether your profile is the source of the problems.

  See "create a profile":

  • https://support.Mozilla.org/KB/Profile-Manager-create-and-remove-Firefox-profiles
  • http://KB.mozillazine.org/Standard_diagnostic_-_Firefox#Profile_issues

  If the new profile works then you can transfer files from a profile in the new profile, but make sure not to copy corrupted files.
