Firefox Sync lets you synchronize bookmarks, add-ons, browsing history and other information across multiple devices. This article shows you how to choose these settings. For information on starting a Sync account or managing your devices, see How do I set up Sync on my computer?

What information can I share across my devices?

You can choose to sync the following information on your devices:

• Bookmarks: this allows you to access all your favorite sites on all your synchronized devices.
• History: this allows you to access sites you have visited in the past on all your synchronized devices.
• Open tabs: your open tabs on other devices can be accessed from the Synced Tabs button on your computer, and in the History tab on your Android device. See the View synced tabs from other devices article for details.
• Logins and passwords: this synchronizes the usernames and passwords you use to log in to websites. If you use a Primary Password, see Using a Primary Password with Sync for important information on how Sync and the Primary Password interact.
• Addresses: this synchronizes the addresses you use to fill in forms on web pages.
• Add-ons: select this checkbox if you want to synchronize your add-ons across your devices. Add-ons for the desktop version of Firefox cannot be synchronized with the mobile versions of Firefox.
• OptionsPreferencesSettings : this synchronizes Firefox's behavior, such as download actions and pop-up blocker settings, across your devices.
