Windows hotmail live and safari

How come since I was forced to “upgrade” to windows hotmail live, it no longer works with Safari? How can I re-establish connectivity?

Via Firefox, apparently.

The “upgrade” worked for me in Safari for a week or two, but for the last few days has reverted to the old graphic look and “unavailability.”

This latest upgrade made me drop Hotmail after 10 years and switch to Gmail. I’ve been happy ever since.
