Features & Capabilities

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.

User Reviews

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.

Pros

Was very easy to use and worked well when functional.
Helped prevent sending read receipts on Facebook Messenger.
Appreciated by longtime users for its purpose.

Cons

Currently does not work with the new Facebook design and updates.
No updates or support since around 2017, leading to it being effectively dead.
Causes Facebook Messenger to be disabled or not functional when enabled.
Users report it being useless and blocking Messenger connection.

Is FB unseen 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.

FB unseen requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

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.

FB unseen is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
