Disconnect for Facebook is a Firefox WebExtension designed to enhance user privacy by blocking Facebook-related tracking on third-party websites. This tool effectively prevents Facebook from monitoring the pages users visit while still allowing access to their Facebook accounts. Its primary features include a low memory and CPU footprint, making it a lightweight addition to the browser, and an easy toggle option directly from the toolbar button for user convenience.

The extension provides a visual badge on the toolbar that indicates the number of blocked requests on the current webpage, allowing users to see its effectiveness in real-time. Activation is straightforward; users simply need to click the toolbar button to enable the blocking feature, indicated by a red color. This new WebExtension implementation is noted for being more stable and lighter than previous versions, ensuring a smoother experience while browsing.
