About this extension
Temp Mail Free provides a fast, disposable email address directly from your Firefox toolbar.
Generate a temporary email address without registering, copy it with one click, and use it for sign-ups, verification emails, free trials, downloads, and websites you do not fully trust.
Features:
• Generate a temporary email address instantly
• Copy the address with one click
• See how long the mailbox remains active
• View the number of received messages
• Change to a new temporary address at any time
• Open the matching inbox securely on TempMailFree.org
• No account or personal email address required
• Receive-only service
When you click Inbox, the extension opens TempMailFree.org and securely connects the website to the same temporary mailbox being used by the extension.
Data transmission disclosure: To provide this functionality, the extension exchanges a randomly generated temporary email address, a short-lived mailbox access token, mailbox expiration information, and incoming message summaries with TempMailFree.org over HTTPS. This information is used only to provide the disposable mailbox and inbox requested by the user.
The extension does not read browsing history, inspect unrelated websites, collect form data, inject advertisements, or access your permanent email account.
Temporary mailboxes and messages expire automatically. Do not use disposable email for banking, cryptocurrency, healthcare, password recovery, or other sensitive accounts.
