Trackkr од Ye Lin Aung

Trackkr records how long the active Firefox tab is open and sends the page URL, title, start time, and end time to a Trackkr daemon running on your computer.

The Trackkr daemon is required. The extension communicates only with its authenticated loopback endpoint. The daemon forwards accepted activity to the Trackkr server configured by the user.

Use the toolbar popup to check the daemon connection and pending queue. The settings page accepts the daemon URL and access token and lets you exclude selected sites from tracking.

Private browsing activity is never stored. Failed deliveries remain in the browser and retry later, up to 500 records or 14 days.
