In a new platform update blog post last Thursday Facebook has announced it will start enabling secure HTTPS connections by default, for all users. Although Facebook has offered HTTPS since January 2011, up until now it has always been opt-in, mainly because of performance concerns. Apparently Facebook now feels confident they can roll this out to everyone, without a serieus impact on performance. The feature will start rolling out to users in North-America starting this week, with the rest of the world following “soon”. For those that value speed over safety, you can still opt-out. But you would be wise not to login to Facebook when on a public WiFi network.
