This Firefox extension automatically checks for your online web-based accounts such as Gmail, Yahoo! or Hotmail and notifies you on the arrival of a new mail. It supports multiple account at the same time and resides as a small icon in your Firefox notification panel. The extension uses the inbuilt Firefox password manager to store your password for enhanced safety, so that neither are passwords stored locally without encryption or are stored online. A lot of web sites are also supported via user scripts. Give it a try and you will never turn back. It is also a “recommended” add-on by the Firefox team.
