Adds an incon in the toolbar (if pinned) with the number of open tabs in the current window. Click once to navigate to a random tab, middle-click to return to the previously active tab.
Features: • The icon itself shows the tab count — no badge, no clutter. • Each Firefox window shows its own count independently. • Left click: jump to a random tab in the same window. • Middle click: instantly go back to the tab you were on before. • No popup, no permissions to external services, no data collected.
