How do I set up Sync on my computer?

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.

Create a Firefox account

You will need a Firefox account to enable sync. To create an account:

  1. Click the menu button Fx89menuButton to open the menu panel.
  2. Click the Sign In button next to Sync and save data.
    Sign in to your Firefox Account
    • The Firefox accounts sign-in page will open in a new tab.
  3. Enter your email and click Sign up or sign in.
    Sign up or sign in to your account
  4. Create a password and enter your age (Why do we ask?) and click on Create account
    create account
    • Take note of the email address and password you used: You'll need them to sign in.
  5. Choose what information to sync. (See How do I choose what information to sync on Firefox?)
  6. You will receive a confirmation email from Firefox with a 6-digit confirmation code. Use it to confirm your account.
  7. Once your account is confirmed, sync is enabled automatically.
Note: To bypass the prompt asking you to connect another device, if shown during the sign-in process, simply open a new tab or window.

Connect additional devices to Sync

A device could be a mobile device (such as a smartphone or tablet), a desktop computer, or another Firefox profile. For more on mobile devices, see:

To connect another desktop computer or profile, just sign in and let Firefox Sync do the rest. To sign in, you'll need the email address and password you used in the previous section.

  1. Open Firefox on the computer or profile you want to sync.
  2. Click the menu button Fx89menuButton, then click the Sign In button next to Sync and save data and sign in.
    Sign in to your Firefox Account

Disable Sync for previously synced devices
