Needs to be contained.

Can't seem to get it to work. Nothing happens on FF 60.0b7. Does this extension only work on regular release?

Awesome!
Now please make a similar addon for Google. They're just as bad as Facebook when it comes to privacy. Thank you in advance.

Thx so much!!!

Excelente, um ótimo trabalho da Mozilla para proteger nossa privacidade.

Finally a step in the right direction. Other browsers should follow.
Maybe make this into a generic add-on that can be used for any website?

An excellent function. one downside is a cannot add other websites, such as messenger.com (another facebook website), to the same container.

Love this! I hate how Facebook had access to so much of my browsing history. Not cool, FB. Thanks Mozilla.
