Disable email forwarding - Stop receiving emails sent through your masks

This article describes how to block email forwarding to stop receiving emails from your masks in your real inbox. If you would like to receive important e-mails only and filter out spam, consider subscribing to Firefox Relay Premium.

Block forwarding to personal email

  1. Click the Firefox Relay button on the toolbar.

    NewManagealias
  2. Click Manage all masks at the bottom of the panel.
  3. Find the mask you want to temporarily deactivate.
  4. Click the downward arrow to expand the options for that mask.
  5. Under What emails do you want to block? Drag the slider from None to All to Block all emails sent to this mask.
    ManageRelayMask

To receive forwarded emails from this mask again, just move the slider from All to None.

Delete an email mask

With a free subscription, you can create up to 5 masks to reuse whenever you need them. You can also delete a mask if you no longer want to use it.

Warning :

Random generated masks:

  • After deleting a mask, emails sent to it will no longer be forwarded to your real mail.
  • Once you delete a mask, it cannot be recovered. ⁨Firefox Relay⁩ will no longer forward messages sent to it.
  • If you use a mask to log in to sites you care about, you should update your login with a different email address before deleting it.

Custom domain masks (Premium):

  • Custom domain masks will be recreated if an email is sent to them and email forwarding will continue. If you no longer need a custom mask, we recommend disabling it by blocking all forwarded emails instead of deleting it.

To permanently delete a mask, follow these steps:

  1. Click the Firefox Relay icon on the toolbar.
  2. Click Manage all masks at the bottom of the panel.
  3. Find the mask you want to delete.
  4. Click the downward arrow to expand the options for that mask.
  5. Click Delete at the bottom right to permanently remove that mask.
  6. A confirmation window will appear informing you that deleted masks cannot be recovered. Check the box to acknowledge the notice.
  7. Click Delete.
