Bewertet mit 3 von 5 Sternen
Initially add-on would download to FF12 but ICON would not appear in toolbar customization menu. Pressing "OPTION" button on FF Add-On page would freeze add-on page and browser requiring task manager to kill FF. By disabling add-on, then re-enabling add-on, then removing add-on, then UNDO removal of add-on, the ICON eventually appeared in the Toolbar customization menu allowing it to then be dragged into toolbar. 5 stars for use, 2 stars for ease of installation.
