Most everyone is pretty aware that big tech companies are tracking you on the web. If you use one of the big "free" email providers, they're scanning your emails. If you watch videos online, they're tracking your preferences.
What many people don't realize is that this is also happening across ALL the sites you visit. If you're logged into Facebook and visit a site that has a "Like" button, Facebook knows YOU were there. They know what news you read, what funny videos you watch, and all those other sites you didn't want anyone to know you visited.
Facebook and Google in particular are building an amazingly rich profile on you to sell to their advertisers. They pretty much know everything about you.
There are many ways to try to avoid this tracking. You can use different browsers for different activities. You can clear history and cookies frequently. You can even build "Site Specific Browsers" to only log into privacy invading sites in silos.
The easiest way to avoid this tracking is using Firefox Multi-account Containers. They allow you to silo all the spying sites into their own little containers. You can interact with your friends on Twitter, YouTube, Google, and Facebook without them seeing what you do on the general web.
The video below will show you how to use this great tool to protect your privacy online.
I'm going to be creating more posts about privacy online over the next few days. Stay tuned for more. If you have questions or want me to cover something else, let me know on Twitter @JustinNoelDev.
