## Description

FB Unseen is a lightweight Chrome extension designed to block Facebook Messenger's "seen" or read receipt feature. With this tool, users can read messages discreetly without sending read confirmations to their friends. This add-on operates seamlessly by disabling the code responsible for read receipts, giving users enhanced privacy and more control over their messaging experience.

A standout feature is the option to manually mark messages as read, allowing you to choose when your friends see you’ve read their messages. Easy to install and minimal in size, FB Unseen is perfect for anyone looking to maintain privacy and avoid the pressure of immediate replies on Facebook Messenger.

## Review summary

Users appreciated FB Unseen for preventing read receipts and its ease of use. However, most reviews report that the add-on no longer works due to Facebook design changes and lack of updates since 2017. The extension now causes Messenger to malfunction or be blocked, making it ineffective and frustrating for users. While previously effective, it is currently considered unusable without developer support.
