DHAKA: Facebook is going to start using app and website data from your browsing habits to provide more targeted ads—and you'll have to opt out if you don't like it.

The feature will provide advertisers with the information required to target Facebook ads more directly, reports the gizmodo.com.

That already happens elsewhere across the internet, but Facebook's previously never used the data in this way, the report added. So, look at a new product online—say, a TV or pair of shoes—and you can expect to seem them on your blue feed.

More control is coming to the ads you see, too: soon, Facebook will add a drop-down menu to ads which will allow you to remove a brand from your ad interests.

Facebook points out, though, that you'll have to opt-out with the Digital Advertising Alliance to stop your browsing habits being shared with advertisers. Privacy activists, you may start shouting... now.
