Firefox has long been an industry leader in security, which is why it’s no surprise that they’re the first large browser to roll out an anti-tracking add-on geared toward making life difficult for everyone’s favorite social media platform: Facebook.
Facebook Container is a deceptively powerful add-on, allowing you to prevent Facebook from tracking and analyzing your browsing behavior while you navigate around the Internet. After installing it in Firefox like any other add-on, you log into your Facebook account inside of the container; from that point on, any Facebook tracking will be confined to the Container tab in which you’re using FB.
The primary purpose of the add-on is, of course, to limit the amount of information that Facebook can extrapolate from your browsing history. There’s still plenty of information that you can give to Facebook simply by scrolling through your News Feed page, but at least they won’t know what size of underwear you’re buying.
Another obvious ramification of using Facebook Container is its ad-blocking capabilities. Unlike a traditional ad-blocker, it won’t force-hide ads; instead, it will hide your activity, meaning you’ll see fewer targeted ads based on your browsing activity and habits. This is likely to cut down on frustration from users who feel inappropriately targeted or singled out by the social media giant’s often-invasive ads.
In addition to its numerous qualities, it also comes with a few downsides—though for the privacy-minded, they’ll probably not feel like game-changers. The main issue is that sharing buttons and those cute little “Like” buttons you see all over the Internet won’t work when you use the add-on since you’ll be logged out of FB everywhere else in Firefox.
Naturally, using the social media buttons outside of the Firefox add-on kind of defeats the purpose of using the add-on to begin with, so this shouldn’t be a huge problem.
You also won’t be able to log into websites that use your FB login information as a credential automatically, which—as Mozilla puts it on the product page—is “to be expected.”
If you’re the kind of person who says “I’d delete my social media accounts, but I need it to stay in contact with so-and-so,” at least once a week, this add-on for Firefox may be for you—and, even if you aren’t a Firefox user, their browser updates over the past six months make switching worth a try.
