Would be great to have this available with FF 52.

I believe this will solve a lot of the problems that Facebook has been having.

Quick question. Is this worth having installed even if you don't have a Facebook account, yet other sites have Facebook options on their sites ??

Worked when I installed it, stopped the next day, maybe due to Nightly installing an update. The container is still there, but it do not open facebook inside it (I am still not logged in outside the container though). I can then manually open the container and open facebook where I am then still logged in

Would be better if i didn't have to log in every time i reload the window.
