NovaNode Masks by NovaNode (MikeNetworks S.à r.l.-S.)

NovaNode Masks gives every website its own email address, without you ever handing out your real one.

Open the toolbar popup on any sign-up page and create a mask for that site in one click. It is filled into the form and copied to your clipboard. Mail sent to the mask lands in your normal NovaNode Mail inbox. When a shop starts spamming you, switch that one mask off; everything else keeps working.

The popup shows the masks that belong to the site you are on, even when the login lives on a different domain, and lets you search, rename, switch off or delete any mask. The right-click menu on any text field offers the same.

Setup takes one sign-in. The extension creates an API key on your account that can manage masks and nothing else; your password is not stored. The key talks to NovaNode's mail server only. No content scripts, no analytics, no third parties.

Requires a NovaNode Mail mailbox (novanode.eu). Interface in English, Dutch, French and German.
