It seems like my Sync has disappeared - how do I access it?

Question

''locking this thread as duplicate, please continue at [https://support.mozilla.org/en-US/questions/1046882 /questions/1046882]''
Reinstalled Firefox and logged in to Firefox sync.
Not syncing properly - not at all, in fact.
Everything is original, no favorites, no add-ons, nothing.
I still have my OLD sync-pass, example: x-xxxxx-xxxxx-xxxxx-xxxxx-xxxxx.
There MUST be a way for me to access my old synced data.
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: [[How to update to the new Firefox Sync]]
