How many times have you experienced this scenario? You go shopping online for a new shirt, speaker or other item. You click on the same one a few times and then decide against it. Suddenly every website you visit has an ad featuring that item, imploring you to reconsider. In an effort to create greater privacy online, Mozilla is now rolling out Total Cookie Protection (TCP) as the default setting on the Firefox app for Android after initially making it available for Firefox users on Windows, Mac, and Linux.

So, what does TCP do? TCP ensures that your cookies aren't being shared across sites. Typically, third-party cookies collect information about you from across the internet to build your virtual identity. Data brokers then sell your information to businesses that will provide you with targeted ads.
