I had enabled firefox sync in my old device synced all the data and then logged out from that device, Now I logged into new system and checked that the firefox sync is not showing any data at all.

Can anybody help me on this as why this happened and if there is any way to restore that sync data.

First, open the sync page of each device/profile and make sure everything is correct. username. password, what to sync . . . .

How many devices/profiles are on your sync?


We need to look at the sync logs. Type about:sync-log<enter> in the address bar of the not syncing unit.
