My FF Home page is a self-made plain htm text file ( file:///.....xxx.htm; only href-links). Usually there is nothing on that NoScript pull-down menu, but now I just noticed there was an item (…live.com). It vanishes when I reload the Home page or NS-menu or go anywhere else, but appears again when I visit the Outlook page and come straight to the Home page.
This ain’t any problem to me, but are there still some menu-refresh things lurking?
