I just reset my windows 8 and Installed Firefox 36. But when I logged in to Sync account, all of my old data was gone. Nothing synced and now I have a sync account which is syncing it's own data. My old passwords and bookmarks are gone. Is there any possible way to access my old data?

Hi Nommon, Without a local back up of the data, this is not possible to restore synced data in past synced dates. I understand that you have a new installation, if there is a folder or profile folder you may be able to find the profile from the previous installation: Profiles - Where Firefox stores your bookmarks, passwords and other user data

Unfortunately I have no other data backup. So, it means all my passwords are lost.


Thanks anyway.

Try to restore a previous version of involved file.

Do you have a C:\Windows.old folder?
