Researchers from Firefox-maker Mozilla emulated his study in 2020 with 52,000 Firefox users, which confirmed Olejnik's findings. Unfortunately, there's no easy way yet to ensure total privacy through browsers, according to Dr Lukasz Olejnik, an independent privacy researcher and consultant, who led a large scale study in 2009-2011 that found web browsing histories can be used by online ad companies to fingerprint individual browsers over time. While Chrome is by far the most widely used browser in the world, there are alternative browsers and ways to improve your privacy when using Chrome.
Big changes are afoot in the ad-sponsored web, and the browser has become a key battleground for end-user privacy.
