Temp Bmail — Disposable Email by Philip Hustle

Temp Bmail brings disposable inboxes into Firefox. Create a temporary address instantly, copy it with one click, and watch new messages appear in the popup. Tap a message to open it on tempbmail.com for the full view. You can change your alias and domain, generate a QR code for another device, and switch among saved addresses from History. The toolbar badge shows an unread count while the extension checks mail in the background.
