Firefox Sync lets you synchronize bookmarks, add-ons, browsing history and other site 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 types of information can I share across my devices?

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

• Tabs: your open tabs on other devices will be stored in the History menu on your computer, and in the Sync tab on your Android device.
• Bookmarks: this allows you to access all your favorite sites on all your synchronized devices.
• Passwords: this synchronizes your login information. This will be disabled if you use a master password
• History: this allows you to access sites you have visited in the past on all your synchronized devices.
• Add-ons: put a check mark in this box 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.
• Preferences: this synchronizes Firefox's behavior, such as download actions and pop-up blocker settings, across your devices.
