Reinstalled Firefox, logged in to Firefox Sync, nothing happens. Everything is original, no favorites, no add-ons, no passwords, nothing. What am I doing wrong? Have my information disappeared? I still have my OLD sync-pass, example: x-xxxxx-xxxxx-xxxxx-xxxxx-xxxxx. There MUST be a way for me to get my synced data back. Please, help me..

hi SolidGamer92, firefox 29 and above use a new sync login system which isn't compatible with the old username/password/sync-key method anymore. you could try this "hack" to get a new firefox version to connect to an old sync account though:

enter about:config into the firefox address bar (confirm the info message in case it shows up), right-click somewhere in that page & create a new string preference named services.sync.username with a value like fake. afterwards you should be able to connect to the old account through the firefox options > sync panel. click on set up firefox sync > i have an account > i don't have the device with me where you can enter your existing credentials.

if this worked and you could import your data successfully, please migrate to the new sync afterwards: Sync your Firefox bookmarks, history, passwords and more
