Facebook typically uses such information to create highly targeted advertising that then appears for the user when they return to Facebook or any of its related products. © Provided by IBT US Facebook typically tracks users around the web with what it calls a Pixel—a small piece of code that site operators place on their site. That code can identify a Facebook user, collect information about what they interact with on the page and show interest in and help advertisers better direct their content for the user.“The pages you visit on the web can say a lot about you. They can infer where you live, the hobbies you have, and your political persuasion,” Nick Nguyen, vice president of Firefox product at Mozilla explained in a blog post. “There’s enormous value in tying this data to your social profile, and Facebook has a network of trackers on various websites. This code tracks you invisibly and it is often impossible to determine when this data is being shared.”
Such tracking practices are considered by many to be invasive, but are not to be confused with the recent controversy surrounding Facebook. In 2014, the company’s data privacy rules allowed for app developers to collect data from the friends of Facebook users without explicit permission.

Facebook Container is not a solution to all data collection, but it can restore a bit of user privacy as a person browses the internet.
To install the extension, install the Firefox web browser and visit the Firefox Add-Ons page for Facebook Container. Click the “Add To Firefox” button and the extension will go to work blocking Facebook’s tracking methods.
