Once you’ve installed Firefox Relay, you’ll see an option to create a mask when you visit a web form. You can generate up to five email masks.

Auto-fill forms with a mask

The Firefox Relay icon will appear in the email field when you visit an online form. Click it to generate an email mask. If the Firefox Relay icon doesn't show up, right-click on the email field and select Generate New mask.

Manually create, copy and paste an email mask

Email masks aren’t just for online forms. If you want to share a mask in other places (e.g.. a message, forum, and more), or if you’re unable to autofill a form, you can generate one and copy and paste it manually.

1. Click the Firefox Relay button on the toolbar.

   

2. Click Manage all masks at the bottom of the panel.
3. Click + Generate New mask and it will appear on the list.
4. From here, you can copy your email mask by clicking the clipboard icon next to it.

   

5. (Optional) Click Add account name to label your mask.
