Tab Focus Sync автор ATClus

Tab Focus Sync is designed to track which browser tab is active. Using Firefox’s APIs (such as browser.tabs and browser.windows), it detects when a tab is activated, updated, or closed, and communicates the focused tab's information to a backend hub via a WebSocket connection built with SignalR. The extension includes mechanisms to automatically reconnect in case of connection loss and to halt tracking after a predefined inactivity period, ensuring efficient monitoring of user engagement.
