Webtime Tracker is a Firefox extension designed to help users monitor their online activities effectively. This subscription-based tool provides detailed insights into time spent on various websites, offering features such as individual website tracking, domain statistics, and total browsing time. Users can visualize their usage through colorful graphs, making it easier to understand their online habits. The program also includes functionalities like backup and restore options, CSV export, and the ability to capture screenshots for sharing purposes.

In addition to its tracking capabilities, Webtime Tracker operates offline and employs a precise algorithm that measures time only when the browser window is active, ensuring accurate data collection. Users can customize features such as idle time intervals and doughnut graph gaps for enhanced readability. With a focus on user privacy, it requires minimal permissions to function, specifically to read the current tab's domain, making it a user-friendly choice for those looking to optimize their web usage.
