What is Firefox Sync ?

If you are already using the Firefox 4 Web Browser, Firefox Sync is a feature that you must not missed. Firefox Sync is a service that lets you synchronize your browsing history, bookmarks, tabs, passwords, and form-fill data from desktop to mobile without interruption. Do not worry about the confidentiality of your Firefox data as the data will be encrypted using the Sync key before it is stored in Mozilla servers. The Sync key is a long string comprised of a combination of alphanumeric characters generated by Firefox Sync.

Note: Firefox Sync employs the symmetric cipher – Advanced Encryption Standard (AES) with 256-bit key and the asymmetric cryptography – RSA with 2048-bit key in encrypting the data. These encryption algorithms ensure the data is stored securely and even Mozilla is not able to read the data.
