## Description

Block Mailtrack is a browser extension designed to enhance your email privacy by blocking tracking pixels used by mailtrack.io within Gmail accessed via Firefox. When enabled, it intercepts and blocks the invisible pixel image that mailtrack.io uses to determine if an email has been opened by the recipient. Users receive a notification each time a tracking pixel is blocked, giving you greater awareness and control over your email privacy. This tool is essential for anyone looking to prevent email open tracking and maintain confidentiality in their communications.
