Mind the Time is a subscription-based Firefox add-on designed to help users monitor their web activity efficiently. It features a customizable ticker that displays the time spent on the current site or the total time spent on the web for the day. Users can switch between various timing modes, including automatic pause during inactivity and options to log only total daily time. The toolbar button provides quick access to detailed statistics, including a summary of time spent over the past 70 days, with weekly and monthly summaries available for deeper insights.

The add-on also includes reminder messages to keep users aware of their browsing duration, and a white list feature to exclude specific sites from tracking. All data is stored locally, ensuring user privacy, with options to delete old data automatically. While the add-on is generally reliable, users may encounter occasional issues with the idle timeout feature due to limitations within the Firefox API. Overall, Mind the Time offers a comprehensive solution for users looking to manage their online time effectively.
