New Web Browser feature: Do Not Track
Tracking takes a variety of forms. Websites use scripts that track what pages you visit online and serve you advertisements based on your interests. If you search for information about Android, you may see Android advertisements on other websites you visit, even if they’re not technology-related. Search engines also show different result pages based on this information. One of the best search engines, which does not track you is Duck Duck Go.
This data about you may also be analyzed or sold.
In fact, enabling “Do Not Track” doesn’t change any browser privacy settings. When you enable Do Not Track, your web browser asks each website you connect to please not track you.
The problem is that most websites simply ignore the “do not track” request. Websites have to be updated to pay attention to this field, and most websites aren’t interested in obeying it.
Currently, Do Not Track is completely voluntary. In the future, it’s possible that some countries will pass laws forcing websites to obey this preference. It’s also possible that some advertising or business organizations may require their members to obey this setting.
On the following website you can find detailed instructions how to enable do-not-track option for Firefox, Chrome, Internet Explorer, Opera, and Safari.
