Facebook's new opt-out for tracking ads is not enough, says privacy expert

Social network provides new opt-out tool for behavioural adverts, but doesn't stop collection of user data

Facebook has rolled out a new tool that allows users to choose whether tracking data from 'Like' buttons and other social elements is used to serve them ads, but privacy experts say the move does not go far enough.

The new privacy tool allows users to opt-out of behavioural advertising, which uses tracking tools that monitor where users go and what they see on the web.
