Outlook Web App Notifications is a Firefox extension designed to enhance user experience by providing timely alerts for new emails and reminders. The extension activates automatically when an OWA tab is open or when a new tab is logged into OWA, requiring no additional configuration. It ensures that users remain informed without needing to keep the Firefox window active, as the system notifications and updates to the fav icon and document title keep track of unread emails and reminders seamlessly.

This tool is particularly useful for multitaskers or those who leave their computers unattended frequently. With customizable CSS selectors introduced in version 1.6.0, users can tailor the extension to monitor specific folders for unread emails, enhancing its functionality. The extension operates by checking the OWA interface every second, ensuring that users receive immediate updates on their email status, thereby improving productivity.
