Facebook Container is a new browser extension for Firefox by Mozilla that isolates Facebook from the rest of your browsing history to prevent tracking.
“This extension helps you control more of your web activity from Facebook by isolating your identity into a separate container. This makes it harder for Facebook to track your activity on other websites via third-party cookies,” Mozilla writes in a blog post.
“Rather than stop using a service you find valuable and miss out on those adorable photos of your nephew, we think you should have tools to limit what data others can collect about you.”
Once you’ve got the extension installed, it’ll first delete all your Facebook cookies in Firefox. The next time you visit the social network’s site, it’ll load in a blue-colored tab (which means you’re browsing in a container) and function as normal – except that if you navigate to a non-Facebook site, that page will load outside of the container.
It’s worth noting that sites which require a Facebook account for registering or logging in may not work properly because of the extension; the same goes for embedded Facebook comments on articles. But if you value the privacy of your data, that’s a small price to pay.
Of course, this isn’t going to stop Facebook from collecting or selling data about you through its site and from other sources where it’s connected to your account – but it’s a great start towards regaining control over your data.
