Better Facebook Container автор GenNext

Facebook Container isolates your Facebook activity from the rest of your web activity in order to prevent Facebook from tracking you outside of the Facebook website via third party cookies.

Sometimes you need to allow sites to access Facebook domains - like when they have "Login with Facebook" functionality. Or maybe you'd like to read a news article that includes some images from Instagram. This modification of Mozilla's original Facebook Container adds the ability to whitelist domains from within the extension's toolbar icon, and remove them from the whitelist once you're done.
