Gmail Notifier (restartless) is a browser extension that allows users to receive notifications whenever they receive new emails in their Gmail inbox. It displays a small icon in the browser's address bar, which alerts users whenever they receive a new email. It is restartless, meaning that it does not require restarting the browser after installation. This extension is compatible with most popular browsers, including Chrome, Firefox, Safari, and Opera. It also provides additional features, such as the ability to quickly search emails, mark them as read, delete them, and add labels. Furthermore, users can customize the settings to determine which emails to receive notifications for. This makes it an ideal solution for those who need to stay on top of their emails without having to constantly check their inbox.
Discontinued The extension is no longer updated. The latest version, 0.6.4.1, released in March 2011, is still available for download from Mozilla Addons.
