## Description

X-notifier, also known as WebMail Notifier, is a powerful Chrome extension that monitors your webmail accounts and notifies you of the number of unread emails. It supports multiple popular email providers including Gmail (both Gmail and Google Apps), Yahoo (yahoo.com, ymail.com, rocketmail.com, yahoo.co.jp), Hotmail (hotmail.com, outlook.com, msn.com, live.com), AOL (aol.com, aim.com), as well as Daum, Naver, and Nate domains. 

This extension allows you to manage multiple accounts on the same host simultaneously, making your email monitoring seamless and efficient. Although version 4.0 does not support user scripts due to changes in Firefox, it supports a comprehensive list of other sites via user scripts for enhanced functionality. X-notifier offers a reliable and user-friendly solution for staying updated with your important emails across various webmail platforms without needing to open each service manually.
