IMHO, average (all) users should read release notes, review menus and
preferences for changes with each update.
It is a known Firefox bug as I pointed out in another post in this thread.
The <
http://www.nytimes.com/> version loads just fine.
My belief is that once a user disables protection on a mixed content
page the user won't see the shield again, but I can not confirm that
because I never run into any mixed content pages in my daily routine.
It will be a major PITA to have to activate the shield, and disable
protection on every visit.
I will continue testing bookmarked sites that are not a part of my daily
routine.
