When you set up Firefox Sync on your computer, all of your ​data​ (such​ as your​ book​mark​s, history, pass​word​s and ​open​ tabs​) gets stored securely on the Mozilla servers. Then you can connect other devices (a mobile phone for example) and they will be automatically synchronized, giving you access to all of your information no matter where you are. This article will walk you though setting up Firefox Sync for the first time.
