Protect Message is a free Chrome extension developed by Kakalot. It falls under the category of Browsers and is a subcategory of Add-ons & Tools. This extension aims to prevent peeking on Messenger and Facebook by implementing two optional effects: blurring messages or creating a reverse mirror message effect.

With Protect Message, users can automatically change the appearance of their messages to ensure privacy. By hovering over the message window or line of messages, users can see the modified message with the chosen effect. It is important to note that the extension does not collect any user information, as all changes are handled by the Chrome browser.

The recent change log shows that the developers are actively maintaining the extension by fixing issues and adding new features. Additionally, there is a helpful video tutorial available on YouTube that demonstrates how to use the extension effectively.

Overall, Protect Message provides a simple and effective solution for enhancing privacy on Messenger and Facebook, making it a valuable tool for users concerned about message peeking.
