Restore browser data after a Mozilla account password reset

If you’re on the same device, your browser data is safe since it’s stored locally. Simply sign in to your Mozilla account in Firefox using your new password and select Sync now from the Firefox application menu . For a new device or an older Firefox version that doesn’t support Sync, transfer your data using the Firefox backup assistant.

Restore data on the same device

If you’re using the same device, your data is already safe!

Sign into Firefox with your new password.
Click Sync now in the Firefox menu.

Restore data on a new device

Sign in with your new password on your original device first.
Click Sync now in the Firefox menu.
Sign in with your new password on the new device and sync.

Move data to a new device or use an older Firefox version without sync support

If you are moving to a new device or using a version of Firefox that no longer supports sync, you can transfer your browser data via the Firefox backup assistant as long as you still have your original device.

Recover data without the original device or after data loss

Regrettably, if your original device is unavailable or the data was erased during a crash or wipe, there is no way to restore your passwords, bookmarks, etc.

Difference between browser data and encrypted data

Browser data includes information such as browsing history, bookmarks, saved passwords, and settings, stored directly on your device. This data remains accessible as long as you have the device and haven’t removed the data.
Encrypted data is created when you use Sync. You can choose to sync selected data, which is then stored on Mozilla’s servers in an encrypted form to ensure privacy and security. You can access encrypted data from any device where you’re signed in with your Mozilla account.

Impact on data after a password reset

If you reset your password using a recovery key, you will retain access to encrypted data. Without a recovery key, encrypted data on Mozilla’s servers is erased for security purposes, while browser data on your device remains unaffected, allowing you to restore your settings.

Note: Resetting your Mozilla account password doesn’t impact subscriptions or payment details, as these are managed separately.
