How can I use my synched account on another PC?
Hello I've synced my PC's firefox on my account but I have no access to that synced data because my domain has been changed. How can I use the data on that synced account on my new domain and firefox?

If you can't receive and respond to an email from the Sync accounts / Firefox Account server there is no way to get data out of Sync. But your "data" is still on the devices that you had connected to Sync.
Setup a new Firefox Account with a current email address from your most used device. Then connect your other devices, along with the new device.
