Here's the
german test page, the only I know. Maybe there's an englisch page too, but I don't know it.
For me OW fails the test, so I've turned off any saving of user names and passwords. Although for FF and Seamonkey. All of them are failing the test.
The latest Apple security update doesn't change anything.
So I prefer to stop all storing of my user data until there will be a fix of the problem.
