Facebook Container is a Mozilla plugin that allows you to access social networks with greater privacy protection in Firefox. As an extension, the program keeps Facebook, Messenger and Instagram isolated from the rest of the browser and prevents those websites from accessing cookies, as well as the use of user tracking mechanisms.
