One Time Message

Create oneOne Time Message - One-Time, Self-Destructing Links-time secure messages from any page using OneTimeMessage.com.

Features & Capabilities

Turn the page you’re on into a one-time, self-destructing link you can share with confidence. Add an optional short note (e.g., context or instructions), click Generate Secure Message, and copy the single-use URL to send anywhere.

How can it help you

1: Captures the current page URL and lets you add a short message. 2: Generates a one-time link that auto-expires after first open. 3 :Optional password: add a passphrase for an extra layer of protection. 4: One-click Copy to share your secure link instantly.

How your data is protected

1: All messages are protected using AES-256-GCM, an authenticated encryption scheme (AEAD). That means: 2: Confidentiality + Integrity: the content is encrypted and includes a built-in authentication tag to detect tampering. 3: Zero-knowledge design: we don’t need to know your password to create or deliver the one-time link.

Why use it

1: Share sensitive pages or notes once—no lingering links. 2: Add context with a quick message so recipients know exactly what they’re opening. 3: Strengthen privacy with a password-protected one-time link when needed. activeTab Justification

Why we request activeTab

We use activeTab only when user click the extension button to read the URL (and optionally the title) of the currently active tab. This lets us prefill your message with the page link you’re sharing—without asking for broad site access or reading page content.

Access is temporary and limited to the tab you interacted with; we don’t: 1: Run scripts on pages 2: We don’t collect browsing history 3: And we never store the URL unless "The User" choose to include it (optional) in their message payload - even when stored in the message, it is an encrypted message using AES-256-GCM (AEAD) which we are unable to decrypt. activeTab is the least-privilege way to support “share current page” functionality.

Is One Time Message Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

One Time Message requires very minimum permissions.

Risk impact analysis details
  • High Allows reading and modifying clipboard content, which can be sensitive, posing a moderate privacy risk.
  • Low ******* ****** ** *** ********* ******** ******************
Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

One Time Message is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
