i want to delete facebook container. how do i do it

I really appreciate the effort from Mozilla to protect our personal data, but this blocks Workplace, which is very inconvenient! I really hope they can address this issue soon.

It works fine on my Windows destop, but is not available for my mobile and my tablet as they are on Android - but I go on FB far more on those devices than on my work PC...

When activated, facebook is out but at the same time I'm unable to log to gmail or other websites (without using facebook-login dear trolls).
Gmail says that my browser is not secured and ask to install a recent one. Other websites ask for recaptcha and repactcha is unable to work properly when this add-on is activated.. This require to be improved.

Edit: It shows the "Installation aborted because the add-on appears to be corrupt." error if you've changed the extensions.allowPrivateBrowsingByDefault toggle in about:config. Now it's working fine.

I am raising my rating because there is a disable button & I don't have to uninstall to shut it off. [So I can still play Facebook games]
Couldn't find one before.

How do i hide the container button, It keeps getting in the way of some images.
I like it but it's just an annoying floating button at this point.
