So, i just downgraded my pc from windows 8 to 7 because some issues. I only used W8 for couples weeks before i decided w8 is not for me. When i installed firefox and begun to sync my account, it only synced my bookmarks and the theme for my top portion of page (the title and the tollbar) and not my add-ons and history eventough i'm sure i synced it before i reinstalled my windows.

After the reinstall on Windows did you change the password or save a back up of the profile? Since its encrypted by the password, the data is not retrievable after you change the password. If you have a back up of the profile try this to restore: Back up and restore information in Firefox profiles

Another look under the hood if you are still having trouble:

  • 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
