I have Firefox Sync running on my laptop, my desktop and on my smartphone too. If someone stole my phone... how can I stop Firefox Sync only on that device, from my laptop or desktop? I only know how to disable firefox sync on the device I want to disable. But if the device is not with me anymore... What should I do? If I stop using Firefox Sync on my desktop, my laptop will not sync anymore..

You'll need to change your Sync password and then reconnect things using the new password. For more detail, read here:
