## Description

This Firefox add-on, named "WhatsApp Chat Highlighter," is designed to enhance the user experience on WhatsApp Web. It specifically targets the issue of managing multiple chat conversations, particularly distinguishing between muted and unmuted chats. The core functionality of this add-on is to visually gray out all muted chats in the WhatsApp interface. This feature makes it significantly easier for users to focus on important, active conversations without being distracted by muted chats.

The add-on operates seamlessly within the Firefox browser, integrating directly with WhatsApp Web. When a chat is muted on WhatsApp, this add-on automatically detects the change and alters the visual appearance of the chat to a grayed-out state. This visual differentiation helps users quickly scan their chat list and prioritize conversations that require immediate attention. The add-on is especially useful for users who manage a high volume of messages and want to maintain an organized and efficient communication flow.

In summary, the "WhatsApp Chat Highlighter" Firefox add-on offers a simple yet effective solution for improving chat visibility and management on WhatsApp Web, making it easier for users to navigate through their messages and focus on what's most important.
