1] Create a Firefox Account

Before setting up Sync, you must ensure you have a Firefox Account. If not, then here’s how you can create it!

Here’s how you can do so:

  • A new tab opens, where you have to press the sign-up or sign-in and complete the process of your choice.
  • Further, add a password, input your age, and select Create Account.

After creating your Firefox account, you must configure the sync per your preferences. The following steps will help you proceed with it.

2] Select the Data that you want to Sync

After creating an account, your next step should be choosing what to sync. Many of you would want to Sync only specific data rather than all. Hence, it’s crucial to select. The methods for doing so differ on PC, Android, and iOS.

Here’s how you can do so for each of them!

It’s noteworthy that Firefox automatically saves these sync changes. However, we recommend you refresh the browser to save the changes manually afterward. It’s because an unstable internet might disrupt the process of automatic syncing.

3] Setup Firefox on the Device where you want to Sync

Since you have set up sync, you can access the information from any other device. To do so, you have to configure your profile here, also.

Follow the steps given below to do so:

  • Download Firefox on your device and open its Menu
  • Press the Sign In button and sign in with your profile where you had set up the sync
  • Tap on Sync Now, and it will sync all the data that you select.

Thus, you have successfully set up sync on Firefox.

4] Disable Sync for Previous Devices Connected with Firefox [Optional]

If you have used Firefox sync before, you would know how to do so. However, there are instances where you won’t need to Sync on your devices anymore.

If you have synced for any previously connected devices, you must log out of your account from that specific device.

Follow the steps given below to do so:
