- sfink 6y agoAh, but if you use https://addons.mozilla.org/en-US/firefox/addon/tab-stats/ https://addons.mozilla.org/en-US/firefox/addon/tab-stats/ then you can not only get the count, but also be able to mass-close large numbers of tabs (eg specific duplicate URLs, or everything for specific domains). A tab hoarder's best friend. (Pretty clever to use telemetry for this, though.)
