Chrome/Firefox/Safari/IE: When you visit a website, your data about the visit is likely sent to advertisers, or kept by the website. A free browser add-on Do Not Track Plus will tell you what sort of data is being collected, and will also block those attempts to share your information.

You might think of it as a bane to install such add-ons but with recent news about Google and other companies bypassing the privacy settings of Safari users and Internet Explorer users to track them, you'd think twice.

Once installed, it will you when a website tries to send data to other companies and blocks it. Do Not Track Plus isn't an ad blocker, so you'll still see ads.
