There’s been a lot said about privacy on Facebook recently, that I won’t go over or comment on at the moment.
Given Google’s recent move to supporting HTTPS on the search page I was starting to check other sites for the same. I was slightly surprised to find that Facebook does indeed allow HTTPS connections and then even more surprised to find that chat doesn’t work (“disabled on this page”) – possibly an area this would be most warranted.
I can’t think of a good reason why this would be the case – perhaps more investigation is required!
