Invisible Message for Facebook™ ავტორი Vũ Thành Trung

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

1. Install the extension in your browser
2. Open the extension popup and enable the encode/decode toggles
3. On Facebook Messenger, wrap your secret text with > and < characters:
   Hey! >This part will be invisible< to most people
4. 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
