small and effective

it does not waste any space on the toolbar

shows the number on the top-right corner in the place as the tabs, just before the minimize window button

works perfectly on FF v38.0.5, and updates on opening or closing tabs

This review is for a previous version of the add-on (1.9.9.1-signed).
