How do I set up Sync on my computer?

(Redirected from What is Firefox Sync?)

A Firefox Account lets you sync your data and preferences (such as your bookmarks, history, passwords, open tabs and installed add-ons) across all your devices. It's free to use.

Important: Sync is not a data backup service. Users should continue to perform regular backups of their Firefox profiles to prevent loss of data.
