L.O.C for Windows

Overview

L.O.C. (Multiple Tools for Facebook) is a free browser extension that adds extra privacy and control features to your Facebook account. It bundles several utilities designed to help you manage interactions, secure personal data, and customize how your profile behaves on the platform.

Core capabilities

• Message Counter — tracks message activity so you can see conversation volume and spot unusual traffic.
• Privacy Changer — offers settings to tweak visibility and request handling, helping you limit who can contact or view parts of your profile.
• Profile Picture Guard — prevents direct downloads and other unwanted uses of your profile photo.

Security and privacy advantages

L.O.C. focuses on preventing unauthorized access and reducing unwanted exposure. Key protections include blocking downloads of profile pictures, hiding read receipts for messages, and offering tools to screen or control friend requests. These features can reduce tracking and give you tighter control over what others see.

Installation and compatibility

The extension is straightforward to install and integrates into Chrome with minimal setup, making it user-friendly for most people. However, it is currently only available for the Chrome browser, which means Firefox, Edge, Safari, and other browsers are not supported — an important limitation if you use a different browser.

Who will benefit most

This add-on is best for Facebook users who prioritize privacy and want simple tools to manage interactions without digging through Facebook’s native settings. If you need cross-browser support, though, you may want to consider alternatives because of the Chrome-only availability.

Summary

L.O.C. is a lightweight, easy-to-use extension that offers useful privacy and profile-management features for Facebook users. It provides meaningful protections and useful utilities, but its restricted browser compatibility may be a deciding factor for some users.
