"N script(s) available" menu item disappeared

[Riajyuu]

When greasefire(2) was moved to Firefox option menu (i.e. in the sanwich button) or other extension like Puzzle Bar by quicksaver and restarted the browser, the "N script(s) available" menu item will disappeare and will re-appear ONLY if you move back to the original position and restart the browser again.
PS on ff 44 release.
