BERLIN: If you regularly check your Facebook account while travelling, be sure to use an encrypted connection. That way you can make sure no one is peeking at what you do on the online social network.
Facebook does offer an https standard, but its activation is not automatic. To do so, users have to go to Account, then Account settings and then to Security.
There, under Secure Browsing, pick the option to Browse Facebook on a secure connection (https) when possible. But https has two disadvantages: it makes the connection slower and it disables some Facebook functions.
