How to Sync Firefox Bookmarks, Tabs, History, and Passwords Across Devices

Firefox Sync Featured

Firefox comes with a feature that allows you to sync your browsing data across multiple devices. This is very useful, especially if you use Firefox on different Windows, Mac, Linux, Android, or iOS devices. Here we show you how to sync Firefox bookmarks, tabs, history and passwords across all devices you are using.

What Is Firefox Sync?

Firefox Sync is a user account set up with Mozilla (the company behind Firefox). It allows you to sync your Firefox browsing session online and with other devices. With Firefox sync, you can view your mobile browsing history on your PC, for instance.

Synchronizing your Firefox bookmarks, tabs, history, and passwords allows you to share and access them across your connected devices.

Frequently Asked Questions

What happens after you sync your Firefox account?

After syncing your Firefox account, you can access your browsing data, such as bookmarks, tabs, history, credit cards, logins and passwords across all your devices.

How to secure my Firefox sync account?

In the Sync settings page, there are options for you to add a secondary email and enable two-step authentication. It is strongly recommended that you do both to secure your Firefox sync account. In addition, you can also add a recovery key to restore your information when you forget the password.

Does it sync my add-on settings?

By default, Firefox will only sync add-ons that you have installed. For their settings, it depends on whether the add-on developers have added support for syncing settings.

Can I have different add-ons in an enabled state on different devices?

Yes, but you need to go to the about:config page and change the services.sync.addons.ignoreUserEnabledChanges flag to true. If the flag doesn’t exist, you will have to create it manually. With this flag enabled, Firefox Sync will not process changes to the add-ons of current device with the enabled state of add-on records from the Sync server. However, local changes on the device will be synced to the server and will propagate to other devices that don’t have this flag enabled. Check out this guide for more about:config tips.

Lastly, note that Firefox Sync is not an online backup tool. You still need to do all you can to protect your online privacy.
