CHEN AND NATASHA SINGER NEW YORK TIMES Say youre doing a Web search on some- thing like the flu. The next thing you know, an ad for a flu remedy pops up on your Web browser, or your video streaming service starts playing a commercial for TylenoL The content of those ads is no coincidence.

Digital ads are able to follow people around the Internet because advertisers often place invisible trackers on the websites you visit Their goal is to collect details on everywhere you go on the Internet and use that data to serve targeted ads to your computer, smartphone and connected television. Our privacy is completely under assault with all these connected devices' said Jeremiah Grossman, the founder of WhiteHat Security, a Web security firm. So what better time to get a head start on defending yourself against Web snoops? Many companies offer tools to help obscure your digital footprints while youre browsing the Web. We researched and tested four tracker blockers and found their results varied widely. In the end, the app Disconnect became our anti-tracking tool of choice.

We took a close look at four free privacy tools: Ghostery, Disconnect, RedMorph and Privacy Badger. We tested them with the Google Chrome browser on the top 20 news websites, including Yahoo News, CNN. The Huffington Post and The New York Times. The tracker busters generally work in similar ways. You download and install an add-on for a Web browser like Chrome or Mozilla Firefox.

The anti-tracking companies each compile a list of known Web domains that sen trackers or show patterns of tracking senices. Then when someone connects to a website, the tools prevent the browser from loading any element that matches their blacklist. Ghostery Ghostery, a popular tracker blocker, was the most difficult to set up. When you install it, it asks you to manually select the trackers you want to block. Our problem with that approach is that there are hundreds of trackers, and most consumers probably wont recognize the vast majority of them, putting the onus on users to research which specific senices they might wish to block.

Scott Meyer, the chief executive of Ghostery, said this had been a deliberate design choice. When trackers are blocked, parts of websites may not function, so it is less confusing to let users experiment and decide which ones to block on their own, he said.
