Using AdBlock Premium's Backup & Sync Feature

By unlocking AdBlock Premium you get access to our Backup & Sync feature, which allows you to share your AdBlock settings across all of your AdBlock extensions. Using this feature will ensure that all of your filter lists, custom filter rules, allowlists, and other AdBlock settings remain the same across all synced extensions. Backup & Sync is available on desktop browsers for Chrome, Firefox, and Edge. Backup & Sync is not available on mobile devices.

In order to use the Backup & Sync feature, you must unlock AdBlock Premium on each device that you want to sync. You do not need to make additional donations. Just use the email address associated with your payment to unlock AdBlock Premium on any additional devices.

To add an extension, open your AdBlock menu in the upper right-hand corner of your browser, and select the gear icon. Under Premium, select Backup & Sync. Click Add this Extension, provide a name for the extension, and click Add.

Once you’ve set up devices as Synced Extensions, their settings will be shared in each instance of the AdBlock extension.


Using your AdBlock Premium email address, you are welcome to sync your AdBlock extension on as many devices as you’d like without making additional donations. Enroll any device you’d like to sync into Premium, add them each as extensions in the AdBlock menu, and sync away!
