Features & Capabilities

Invisible Message

A browser extension for sending hidden messages on Facebook Messenger using invisible Unicode characters.

What it does

This extension encodes your messages into invisible Unicode tag characters before sending them. Messages appear completely blank to users without the extension, but are automatically decoded for those who have it installed.

How to use

Install the extension in your browser
Open the extension popup and enable the encode/decode toggles
On Facebook Messenger, wrap your secret text with > and < characters: Hey! >This part will be invisible< to most people
Send the message normally

Recipients with the extension will see the decoded hidden text. Everyone else will see only the visible parts of your message.

Features

Independent controls - Toggle encoding and decoding separately
Works everywhere - Compatible with facebook.com, messenger.com, and web.facebook.com
No data collection - All processing happens locally in your browser
Cross-browser - Supports both Chrome and Firefox

Is Invisible Message for Facebook™ 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.

Invisible Message for Facebook™ requires a few sensitive permissions. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious.

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.
