adverts could actually still be tracking you

The recent explosion in people installing ad blockers for their browsers may have an ironic side effect: identifying them to advertisers. French researchers digging into online privacy issues have built on a 2010 study by the EFF that used people's browser configurations to identify individuals. The researchers account for the 2017 internet: they look at what browser extensions people have and what social media services they are logged into. The results have been as dramatic as the earlier study: people's browsers serve as highly effective identifiers. We ran the researchers' online test and got a privacy of precisely zero: meaning that of the 4,000+ people that have run the test so far, our browser had a unique fingerprint. wrote:
