Popular Mechanics reports that those who worry about their privacy on Facebook, but still need to use the social media site for whatever reason, do have options. Mozilla just released a Facebook Container Extension. "Once you set up the extension, Firefox deletes all your Facebook information from itself and only connects to Facebook from inside a software "container." The practical result is that you can look through a sort of one-way mirror to see into Facebook, but Firefox keeps Facebook from looking out," Eric Limer writes in the magazine. Third-party apps that use Facebook to login won't work, and you can't Facebook like or Facebook share items in the non-Facebook world. There are other options, including blocking all of Facebook's subdomains directly (but that disables the site), or installing the Privacy Badger extension.
