Managing your Sync data

The following procedures show you how to select, decrease, reset, clear and request more quota for your your Sync data. How do I select the data that I want to sync? Note: For security reasons, the master password is not synced even if passwords and preferences are selected.

   Open the Sync options window.
   In the Sync My section, select the check box for each data type you want to sync: bookmarks, passwords, preferences, history, open tabs, add-ons.

Add another computer

Do these steps on the computer you are trying to add to Firefox Sync.

   At the top of the Firefox window, click the Firefox button and select Set Up Sync. The Firefox Sync Setup window will open.
   Click I Have an Account.
   Since you're not near the device with Sync already set up, click the I don't have the device with me link.
   Sign in to your Sync account:
       Enter your account email address
       Enter your password
       Enter your Recovery Key
       Then click Next 
   You will see a Setup Complete screen. Click Finish to complete adding this device to your Sync account.

Did you make a backup copy of the Sync key?
If not then you can't access that data on the Sync server and this data is lost.

Note that Sync isn't meant to be used as a backup device. It is always better to backup your personal profile data locally.
