Want to contain Facebook? Mozilla’s got you. They have a Facebook Container Extension.
Mozilla, maker of the Firefox browser, said in a blog post on Tuesday that it created the extension to help “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.”
Facebook has come under intense scrutiny after a whistleblower revealed that a third-party app harvested millions of users’ information, some without permission, to build psychological profiles of those users in an effort to better serve them advertising information about the 2016 election.
While allowing third-party use of data is common, a lot of Facebook users, it seems, weren’t aware of what, exactly, was being done with the information they put on the social network.
“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,” Mozilla says in its blog post about the extension. “That includes us: Mozilla does not collect data from your use of the Facebook Container extension. We only know the number of times the extension is installed or removed.”
Facebook has said it no longer will allow the sort of data harvesting done by the company that caused the controversy, a British firm called Cambridge Analytica, that allegedly used the information to try to influence both the American presidential election in favor of Donald Trump, and the vote in Britain over whether to leave the European Union.
“When you install this extension it will delete your Facebook cookies and log you out of Facebook,” Mozilla says. “The next time you visit Facebook it will open in a new blue-colored browser tab (aka ‘container tab’). In that tab you can login to Facebook and use it like you normally would. If you click on a non-Facebook link or navigate to a non-Facebook website in the URL bar, these pages will load outside of the container.”
